Mainframe Assembler Analysis
|The SimoTime Home Page|
SIMOX390 is a mainframe Assembler Analysis Tool. This version of SIMOX390 runs on a Windows System and scans a mainframe assembler source member (or a list of members) that have been downloaded and identifies the macro and copy files used by the program or list of programs. This tool should be used in conjunction with a pilot test that would actually assemble, link, and execute a sample test case of an actual application.
This tool is provided to assist in the initial evaluation phase of offloading, maintaining, developing, and/or testing of mainframe assembler programs using Mainframe Express from Micro Focus (refer to http://www.microfocus.com) SIMOX390 is also very useful for getting a quick overview of the mainframe assembler programs and their dependent macro and copy files.
We have made a significant effort to ensure the documents and software technologies are correct and accurate. We reserve the right to make changes without notice at any time. The function delivered in this version is based upon the enhancement requests from a specific group of users. The intent is to provide changes as the need arises and in a timeframe that is dependent upon the availability of resources.

SIMOX390 requires approximately 800K of disk space. Windows/XP, Windows/7 or Windows Server is the required operating system. The SIMOX390 program, this documentation, the Installation Verification Procedure (IVP) and examples are provided in a zipped file.
To install SIMOX390 and run the IVP and sample create a directory as follows.
C:\> md SimoLIBR
C:\> cd SimoLIBR
C:\> C:\SIMOLIBR> pkunzip simox390.zip
The following shows the Command Line syntax for running the Installation Verification Programs (IVP's).
C:\> C:\SIMOLIBR> X390IVP1
C:\> C:\SIMOLIBR> X390IVP2
The X390IVP1.cmd uses the command line interface to access a single mainframe assembler member and it's dependent macro and copy files.
The X390IVP2.cmd uses the command line with the LISTFILE function to access multiple mainframe assembler source members and their dependent macro and copy files.
SIMOX390 will scan mainframe assembler source members that have been downloaded to a Windows System. In addition to scanning the main source member SIMOX390 will attempt to find and scan dependent macro and copy files. To scan a single 370 assembler source member and it's dependencies use the following command.
C:\SIMOLIBR> SIMOX390 filename.MLC
To scan a list of member names use the following command.
C:\SIMOLIBR> SIMOX390 filename.ext LISTFILE
where filename.ext is the name of an ASCII/TEXT file that contains a list of source members to be scanned.
An easy way to create a LISTFILE is to use the following command.
C:\>dir *.MLC /B /A-D /ON>filename.ext
The /B option will cause the dir command to only display the filename. The A-D option will prevent sub-directory names from being included in the list. The /ON option will cause the dir command to organize the directory list in name sequence. The filename.ext will cause the dir command to pipe (route) the directory listing to the specified file.
Note: if you are using EXEC CICS within 370 assembler applications then you will need to run the analysis tool for the filename.CAP files. The command line with required parameters is as follows.
C:\SIMOLIBR> SIMOX390 filename.CAP
SIMOX390 uses the following environment variables. The X390LIB1 environment variable must point to the directories containing the macro and copy files. The X390LIB1 environment variable may contain concatenated directories separated by a semicolon. If X390LIB1 is not specified then the current directory will be the only directory searched for macro and copy files.
The preceding statement is an example of setting the X390LIB1 environment variable that will be used by SIMOX390 to search the current directory and the c:\mfe\mfasm\include directory for macro and copy files.
The X390LOG1 environment variable will map the name of the log file to a specific drive, directory and name. The log file is an ASCII/Text file.
The MACEXT environment variable will define the extensions to be used when accessing HLASM Source Members that are Macro Files.
The optional parameters are as follows.
|Optional Command Line Parameters for SIMOX390|
The functions provided by SIMOX390 are described in more detail in the following sections.
SIMOX390 will scan a single source member or a list of source members and produce a listing of the macro and copy files used by each source member. SIMOX390 will also scan each of the macro and copy files for additional, nested macro or copy files.
In order for SIMOX390 to complete this analysis the source members, the macro files and the copy files must be accessible from the PC. The X390LIB1 environment variable is used to identify the directories where the macro and copy files are stored. The X390LIB1 environment variable may contain concatenated directories separated by a semicolon. If a macro or copy file cannot be found for analysis then and error message is displayed and written to the SIMOX390.log file.
The following is an example of a group of records that are written to the user log file when a High Level Assembler (HLASM) source members is scanned and analyzed.

The preceding is an example of entries in the user log file after running the Assembler Analysis Tool. The following provides additional information about the individual records in the user log file.
|1-5||The first four records are program messages that identify the start of program execution. The START record shows the date and time the SimoX390 program was started.|
|6||The CLINE record shows the command line parameters.|
|7||The *SYSIN record shows the name of the primary source member. The 01 indicates the main program or first level of possible nested members.|
|8||The COPY record shows the name of a copy member. The 02 indicates this is the second level of nesting.|
|9-10||The MACRO record shows the name of a macro member. The 02 indicates this is the second level.|
|11||The *INFO record indicates a condition was encountered during the member scanning process and requires further review by the user.|
|12-15||Record 12 contains "** =" followed by the name of the HLASM Program Member. Records 13-15 contain "** +" followed by the name of a dependency member name.|
|16-22||The *LIBR records identify the concatenated dependency libraries that were defined by the user via the X390LIB1 environment variable.|
|23||The *USER record identifies the user-defined value for the MACEXT environment variable. This defines a concatenated string of possible extensions for MACRO file names.|
|24-27||The *MACEX is the internal list created by the Assembler Analisis Tool.|
|28-33||The STOP statement shows the date and time the SimoX390 job was completed. The remaining records are program messages that identify the program that has completed execution.|
If the CALLPLUS parameter is specified on the command line then SimoX390 will display (and write to the simox390.log file) each source statement that is a CALL, LINK or LOAD. If a literal is used to identify the member being referenced then the task is complete. If a variable or register notation is used in the CALL, LINK or LOAD statement then additional effort will be required. SIMOX390 does not attempt to resolve variable or register content. Also, in some cases this information may not be available until execution time.
C:\SIMOLIBR> run SIMOX390 filename.ext LISTFILE CALLPLUS
The preceding line is an example of the command to cause the CALL, LINK and LOAD analysis to be enabled.
If the SVC parameter is specified on the command line then SIMOX390 will display (and write to the simox390.log file) each source statement that contains the SVC operation code. Since the entire source statement is displayed the SVC number or mnemonic value will also be displayed.
C:\SIMOLIBR> run SIMOX390 filename.ext SVCTRACE
The preceding line is an example of the command to cause the SVC analysis to be enabled.
One of the more difficult items to identify is the used of hexadecimal (i.e. non-printable) characters in mainframe source members. On the mainframe this is an accident waiting to happen. When downloading source members to the PC platform it is a recipe for disaster and needs to be identified as quickly as possible.
Identifying hex characters in assembler source members and their associated macro and copy files is easily accomplished using SIMOX390. The use of the HEX parameter on the command line will scan each member for characters less than x'20' or greater than x'7F'. If a hex character is found then a hex dump of the record is displayed and written to the SIMOX390.log file.
C:\SIMOLIBR> run SIMOX390 filename.ext LISTFILE HEX
The preceding line is an example of the command to cause the HEX analysis to be enabled.
The SimoX390 program provides a user with the capability of quickly understanding the structure and interaction between members for both compile and execution time. For the compile time information, SimoX390 will process a list of assembler source members and create a cross reference list of all the macro and copy files used by each of the members in the list. This document may be used to assist as a tutorial for new programmers or as a quick reference for experienced programmers.
In the world of programming there are many ways to solve a problem. This documentation and software were developed and tested on systems that are configured for a SIMOTIME environment based on the hardware, operating systems, user requirements and security requirements. Therefore, adjustments may be needed to execute the jobs and programs when transferred to a system of a different architecture or configuration.
