Answer Posted / samay simant
PARM: Its a parameter in EXEC Statement to pass data or
provide input to the PGM that EXEC calls.
Regarding system defined parameters:Theses parameters are
passed to the program 'IEWL' ,its the compiler program.
XREF:
This is a COBOL compiler option. Format: XREF NOXREF
Abbreviations: X NOX
IBM-default: NOXREF
XREF requests that the compiler produce a sorted cross-
reference showing EBCDIC data-names and EBCDIC procedure
names (in alphanumeric order) and the line numbers of the
source lines in which they are referenced. It also includes
a listing of DBCS data-names and DBCS procedure names in
the same order as they appear in the source program (unless
the DBCSXREF installation option is selected) as well as a
section listing all the program names that are referenced
in the source program and the line number in which they are
defined (with external program names identified as such).
In the data-name portion of the XREF listing, line numbers
preceded by the letter ‘M’ indicate the data item is
modified by a statement on that line. Elementary names
within a group item referenced in a MOVE CORRESPONDING
statement will also be included in the XREF listing. If
both XREF and SOURCE are specified, cross-reference
information will also be embedded in the source listing
itself
(i.e., at the right hand end of the line to which it
applies).
This information includes line number references as well as
an
indication that a name is undefined (UND), duplicately
defined
(DUP), implicitly defined (IMP), or, if a program name,
externally defined (EXT).
LIST:
This is a COBOL compiler option. Format: LIST NOLIST
Abbreviations: None
IBM-default: NOLIST
LIST requests that the compiler produce a listing of the
generated machine language object code (which is produced
by printing out the corresponding assembler-language source
code). LIST also provides information in the output listing
about: • Global tables • Literal pools • WORKING-STORAGE
LET:No Idea BOSS. If you get any details kindly let me
know.
APOST:
APOST specifies that the single quote mark or apostrophe
(‘) is to be the delimiter character for non-numeric
literals.
RENT:
A program compiled as RENT is generated as a reentrant
object program; a program
compiled as NORENT is generated as a nonreentrant object
program. Either can be
invoked as a main program or subprogram.
