I've run into a problem implementing word wrap. When a word doesn't fit at the end of a field, I need to put it on the next field and pad with blanks. However, I need to distinguish between blanks I use for padding and those blanks the user entered. My best idea so far is to use special characters and then modify the functions for display to replace them with blanks. Initially I have chosen to use hex FE since my charts show that as a non-existent character in both EBCDIC and ASCII. Interestingly, it still maps to a character. I think this idea is the way to go (it is working) but I need a non-blank character that can't possibly be a valid display character. Any suggestions?

How about 0x00?
I don't understand.
Assuming this is driven by keyboard interrupt, If the last char a user entered on line 1 is space, you don't need to word wrap. just
position the cursor on the line 2. If the last char was non space,
just grab the last word.

It doesn't always come from the keyboard. Nor can you only worry about the case where a user is typing at the end of a line. What about if the user is inserting text somewhere else in the line? Or deleting text? The text that is sent from the iSeries is not wrapped, the emulator has to handle that itself. All these cases except the first (using typing at end of line) are now handled.
