I am also baffled by the operation of pattern searches. I have one of my own that looks just as strange: The search is for ("^O" | "^N" | "FF" | "ESC"). The string really contains the control characters. A SEARCH finds some of the characters, but not all--at least on a single pass. If I repeat the search, it will find more characters. If I run it several times it gets everything. I use the TPU procedure to replace control characters with ASCII strings for use in mailing. Maybe I just dumb, but I don't understand either! R.

MAIL sometimes falls in the old bit bucket and I assume that this one never made it to SRI-KL. ------
