Thank you very much Peter, Brian, Smith5646 & Jon.

Yes the Quotes around the name of the PF in EXTNAME('PFNAME') compiled &
worked successfully.

EXTNAME requires Quotes in Free RPG, but not in Fixed-From.

As Jon Paris noted, the rules for EXTNAME are different for fixed vs
free format:

• In a free-form definition, the file-name and format-name parameters
must be character literals or
named constants representing character literals. If a parameter is a
named constant, the constant must
be defined prior to the definition statement.
• In a fixed-form definition, the file-name and format-name parameters
can be either names or character
literals.

In Mohan's original question it's unclear whether the parameter for
EXTNAME is the actual name of the file, or the name of a character
field. Note that in free-form, the parameter for EXTNAME cannot be the
name of a character field; if it's not a character literal, it must be
the name of a named constant representing a character literal.

As Brian noted, this would work:

DCL-DS DS_WMS0104 EXTNAME('LMBJDS104W') PREFIX('W_') END-DS;

or

DCL-C LMBJDS104W CONST('LMBJDS104W');
DCL-DS DS_WMS0104 EXTNAME(LMBJDS104W) PREFIX('W_') END-DS;

But this wouldn't work because the named constant must be defined before
it's used:

DCL-DS DS_WMS0104 EXTNAME(LMBJDS104W) PREFIX('W_') END-DS;
DCL-C LMBJDS104W CONST('LMBJDS104W');

And this wouldn't work because the parameter for EXTNAME, if it's not a
character literal, must be the name of a named constant, not a field.

DCL-S LMBJDS104W CHAR(10) INZ('LMBJDS104W');
DCL-DS DS_WMS0104 EXTNAME(LMBJDS104W) PREFIX('W_') END-DS;

Nearly. Needs quotes around the EXTNAME item, i.e. ExtName('LMBJDS104W')

From the RPG IV Reference:

"• In a free-form definition, the file-name and format-name parameters
must be character literals or named constants representing character
literals. If a parameter is a named constant, the constant must be
defined prior to the definition statement."
