I think that since V5R1, you can use RPG Softcoded Filenames with the
EXTFILE and EXTMBR Keywords in the "F" specifications so you can control
which external file gets opened. You can also code constants, which would
be a good choice if you want to be sure to use a file in QTEMP rather than
one that might be in the library list:
Ftempfile o e disk extfile('QTEMP/X4ATEMP')
Note: Notice that the EXTFILE value is in the form LIBRARY / FILE.
I pulled and example from R.Cozzi's website: here's an example where the
file name is constant, but the member name is variable. (This varies
depending on the user profile, obtained from the program status data
structure, PSDS, which is set up at the beginning of initialization.)
Foptions if f32766 disk extfile('OPTLIB/OPTFILE')
F extmbr(userName)
D psds sds
D userName 254 263
These keywords are only used at runtime. If you code a constant as the
parameter to EXTFILE for an externally described file, the compiler will
not use this keyword to find the external descriptions.
