Getting ASCII Data with PRINt? ALL Query
This program example shows you how to get ASCII data from a listing
display, like the disk catalog or state listing, using the PRINt? ALL query.
There are two things you must keep in mind:
•
You must select the mainframe, which is always SELECT 0 for the
HP 16500C mainframe.
•
You must select the proper menu. The only menus that allow you to use
the PRINt? ALL query are the disk menu and listing menus.
10 ! ****** ASCII DATA *******

50 ! in ASCII form by using the PRINT? ALL query.
