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.
