Step 2 of 2:
This is extremely useful when system documentation has become out of date and system changes are due.
I wrote the program to gather information on all queries. But it wouldn't be difficult to adjust the code for particular libraries only.
The clean up at the end has been commented out to allow later analysis over the files.
The program has little error trapping and assumes you have source file QTXTSRC in QGPL. You will need AS/400 Query and SQL on your machine.

DSPOBJD OBJ(LIB1/*ALL) OBJTYPE(*QRYDFN) +
OUTPUT(*OUTFILE) OUTFILE(QTEMP/RTVQRYW1)
CALL PGM(RTVQRYC1)
DSPOBJD OBJ(LIB2/*ALL) OBJTYPE(*QRYDFN) +

DSPOBJD OBJ(LIB3/*ALL) OBJTYPE(*QRYDFN) +

CALL PGM(RTVQRYC1)
