RE: Help with converting Mainframe file on iSeries

The hex display (F10) of DSPPFM is cool - and once in that mode, F11 puts you in an over/under mode, where each byte takes up only one column - the display value on top with the first nybble just below that, followed by the second nybble below that again.
If you see a bunch of digits followed by a letter (usually "F" or "D"), then it is a packed field - probably. If it's a hodge-podge of characters, often non-displayable, it is probably binary, maybe floating point (rare). At any rate, you are close to the true locations, and you can test what kind of data is there.

Jon, et al, they could always to a cpyf tofile(*print) outfmt(*hex) and
see where the field barriers and types fall...  Also, look at the hex
format of a dsppfm for field positioning and data typing - IFF you know
how to interpret what you're reading...:)  And this late in the day, I'm
not sure I know baudot from morse code! :)
