This test case includes a Job Script and High Level Assembler (HLASM) that will perform functional testing of the Load Halfword (LH) instruction. The results of the functional testing will be written to a user log file. The content of the affected General Purpose registers will be presented using hexadecimal notation.

Table of Contents Previous Section Next Section Description of LH

This test case includes a Job Script and High Level Assembler (HLASM) that will perform functional testing of the Load Halfword (LH) instruction. The results of the functional testing will be written to a user log file. The content of the affected General Purpose registers will be presented using hexadecimal notation.

The two bytes (halfword) located at the storage address specified by operand-2 (x2+b2+d2) is treated as a 16 bit, signed binary integer and is loaded into the rightmost two bytes (bits 16-31) of the register specified by operand-1 (r1). The leftmost two bytes (bits 0-15) of the register specified by operand-1 (r1) are filled based on the sign bit from operand-2. For example, if operand-2 contains a positive value then the leftmost two bytes will be x'0000'. if operand-2 contains a negative value then the leftmost two bytes will be x'FFFF'.

SimoTime Technologies was founded in 1987 and is a privately owned company. We specialize in the creation and deployment of business applications using new or existing technologies and services. We have a team of individuals that understand the broad range of technologies being used in today's environments. Our customers include small businesses using Internet technologies to corporations using very large mainframe systems.

Quite often, to reach larger markets or provide a higher level of service to existing customers it requires the newer Internet technologies to work in a complementary manner with existing corporate mainframe systems. We specialize in preparing applications and the associated data that are currently residing on a single platform to be distributed across a variety of platforms.

Preparing the application programs will require the transfer of source members that will be compiled and deployed on the target platform. The data will need to be transferred between the systems and may need to be converted and validated at various stages within the process. SimoTime has the technology, services and experience to assist in the application and data management tasks involved with doing business in a multi-system environment.

Whether you want to use the Internet to expand into new market segments or as a delivery vehicle for existing business functions simply give us a call or check the web site at http://www.simotime.com
