Either 31-bit or 24-bit addressing for INMOD routines can be used on mainframe-attached systems. The 31-bit mode provides access to more memory, which enhances performance for Teradata TPump jobs with a large number of sessions.

Use the following linkage parameters to specify the addressing mode when building INMOD routines for z/OS systems:

  • For 31-bit addressing: AMODE(31) RMODE(24)
  • For 24-bit addressing: AMODE(24) RMODE(24)
