MVC and MVCL are what I use if I know the actual length, but I'm concerned with the case where I know only bthe maximum length. I want to do a copy until a blank, but stop if that hits the maximum length.

That will copy the terminating character (e,g., blank) and at the same time, preserving the integrity of the string. Anything else beyond it is also copied to the destination. Use blank fill for the destination in case the blank could not be accommodated in source. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
