Usage notes

  • The assembler user exit (CEEBXITA), HLL user exit (CEEBINT), and programmer defaults (CEEUOPT) that are used to initialize the environment are taken from the first valid entry in the PreInit table. Any occurrences of CEEBXITA, CEEBINT, and CEEUOPT in other PreInit table entries are ignored. Unpredictable results will occur if this first entry is deleted or changed.
  • COBOL, PL/I, and C routines must be compiled RENT to participate in this environment
  • You can direct MSGFILE output to either a spool or to a unique file.
  • C memory files are not shared across multiple environments.
  • If the (init_sub_dp,...) interface is used to create additional environments, neither the existing environment, nor the one trying to be created can be POSIX(ON).
  • If a program in the PreInit table failed to load (return code 8 or 40), the identify_attributes CEEPIPI function can be used to help determine what table entry address did not resolve.
