overlay question

[mohammad khan <mohammadakhan@xxxxxxxxx>]

hi, 

i have a question about overlaying 3 records in a dspf.

how do you specify which records ought to be overlaid. i mean, in an
rpg pgm. (which i must write) how do you tell the pgm to overlay rec1
w/rec2 at this point in the pgm and rec3 w/rec4 at another point, so
on and so forth...?

an indespensable link was given to me yesterday at

http://publib.boulder.ibm.com:80/cgi-bin/bookmgr/BOOKS

but i still need to know.

i mean, when you add the overlay kywd. to a rec. in a dspf. (that
works w/other recs. in the same dspf) is it necessary to specify the
overlay kywd. with the other recs. if you don't want them to be erased
when they work with the other recs.?

i hope i haven't confused you w/my wording.

sincerely,

Mohammad
