Command CICS by ASPG is a systems software product designed to migrate CICS from a Macro-Level to a Command-Level environment. Command-Level calls are made dynamically during the execution of Macro-Level programs. Command CICS translates 100% of Macro-Level code to Command-Level code at execution, eliminating the need to rewrite or recompile applications for CICS transaction server migration. It offers performance equivalent to manually converted programs. Command CICS supports all software programs using Macro services. Installation is easy and takes only a few hours, regardless of how many programs are affected. Upon installation, Command CICS will run independently, with little or no monitoring. Missing source code is no longer a problem. It supports mixed-code programming with 100% conversion of Macro-Level programs. Command CICS provides an online transaction to display counts of various types of macro calls converted by Command CICS. It supports the use of Exec CICS ADDRESS CSA. Command CICS offers an online trace facility, resource level security, and application debugging with CEDF. It serves as a cost-effective alternative to migrating to new CICS Transaction systems following IBM's discontinuation of support for CICS Macro-Level code in MVS and VSE.
