You can process a source file in your program. You can use the
external definition of the source file and do any input/output operations
for that file, just as you would for any other database file.
Source files are externally described database files. As such, when you
name a source file in your program and compile it, the source file description
is automatically included in your program printout. For example, assume you
wanted to read and update records for a member called FILEA in the source
file QDDSSRC. When you write the program to process this file, the system
will include the
SRCSEQ,
SRCDAT, and
SRCDTA fields from
the source file.
Note: You can display the fields defined in
a file by using the Display File Field Description command (DSPFFD).
