The u3f user exit converts an ASCII hexadecimal-format string to binary, and sends it to the printer.
results = oconv(str.exp, ’u3f’)
The ASCII hexadecimal characters have to be in matched pairs. If a character with a single digit value (less than x’10’) is to be printed, make sure there is a leading zero.
stuff = "0D0A0000" x = oconv(stuff,’u3f’)
Sends the hexadecimal string "0D0A0000" to the printer (CR/LF, and 2 nulls for linefeed delay.)
