I accept that as a limitation of the 327x data stream design. I've exploited it at times to insert a character such as ';' at the end of a line when the cursor is inconveniently far: Tab to next line. Back-arrow twice. Type ';' ENTER. The ';' scoots to where I want it. If blanks were treated by Edit as ordinary characters, even as 3270 does, that ';' would appear after the blanks. If I didn't want that, I shouldn't have inserted the blanks in the first place. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
