SLIB processing

The runtime unit replaces the ISPF file tailoring interface. In most cases, interfaces to the runtime unit are the same as interfaces to ISPF file tailoring. To improve runtime performance, the runtime unit offers special logic that is designed specifically for JCL Generation.

The runtime unit handles mixed mode processing of compiled and noncompiled SLIBs. However, mixed mode processing is not recommended because it compromises the improved performance that the runtime unit was designed to provide.

All JCL processing flows through the runtime unit. The runtime unit does the following:

  • Resolves all variables
  • Provides numeric data padding
  • Handles I/O
  • Processes standard file tailoring requests, when necessary
  • Builds a report about the JCL generation process
