MAINFRAME - TIP OF THE DAY :
Sometimes it might be helpful to see only 1 or a few records in HEX (rather than the entire file w/ HEX ON).
When VIEWing or EDITing a file use the line command HX to show that line in HEX. To show 3 records, enter HX3. To turn the hex off enter HX (for 1) or HX3 (for 3). Or in the Command area, enter HEX OFF.
