APPENDIX: IECDSECT,IEFJFCBN, AND IEFUCBOB MACRO-INSTRUCTIONS
If you want to use the IECDSECT,IEFJFCBN and IEFUCBOB macro-
instructions, you must either add these roacro-definitions to the
macro-library (SYSi.MACLIB) or place them in a separate partitioned data
set and concatenate this data set to the macro-library. This section
contains the following:
• The forn,ats of the macro-instructions.
• The Job Control and utility stateroents needed to add the rnacro-
definition to the library.
• The macro-definition to be added to the library.
IECDSECT MACRO-INSTRUCTION
This macro-instruction defines the syrrbolic names of all fields in
the work area used by the OPEN, CLOSE, TCLOSE, and EOV routines. Code
this macro-ins"truction with blank name and operand fields, and precede
it with a DSECT statement. Note: The IEFJFCBN rracro-instruction is used
in the assembly of IECDSFCT. The macro-definition for IEFJFCBN nlust be
present in the macro-library (SYSi.MACLIB) for successful definition of
all fields in the work area.
