Hello, Dave:
If you create the object from the DDS source (e.g. PF, LF or DSPF or
PRTF etc.), then the IBM COBOL compilers will do this for you
automatically when you compile your program and reference an "externally
defined" *FILE. For example, below, I show a snippet of code from a
COBOL listing where I have the statement COPY DDS-ALL-FORMATS OF FILEA
(on line 19) and you can see the lines immediately below that show the
"generated" code, with "<-ALL-FMTS" markers.
18 001800 FD
FILEA
19 001900 COPY DDS-ALL-FORMATS OF
FILEA.
20 +000001 05 FILEA-RECORD PIC
X(50). <-ALL-FMTS
+000002* I-O FORMAT:AR FROM FILE FILEA OF LIBRARY
ISS <-ALL-FMTS
+000003*
<-ALL-FMTS
21 +000004 05 AR REDEFINES
FILEA-RECORD. <-ALL-FMTS
22 +000005 06 AKEY PIC
X(10). <-ALL-FMTS
23 +000006 06 ADATA PIC
X(40). <-ALL-FMTS
So, if you really needed to convert DDS source to COBOL source, perhaps
you could just "cut-and-paste" from the compiler listing? This would be
a lot less 'work" than parsing the DDS source. You could even write a
program (or command) that would:
1. create the *FILE (in QTEMP) from the DDS source
2. ensure QTEMP is at the top of the *LIBL
3. generate and compile COBOL source with an embedded "COPY
DDS-ALL-FORMATS OF " filename
4. read the listing spool file and copy the relevant lines (marked with
"<-ALL-FMTS") to a target source member

Looking for a way to have a DDS source file definition translated into a
