Jon's version is the one I posted (I believe). I sent it to you a few months ago. It is the version of strsep that I posted early today to the list.

Jon indicated he had a version of strtok that properly handled "empty fields". I suggest contacting him about your problem, if, as Scott suspects below, that is the problem you are having.

Does anyone know how handle the multiple delimiter issue?? > Unfortunately, the strtok() function has no way of detecting "empty fields" (i.e. places where there are two consecutive delimiters). I think that's what you're asking. In FreeBSD and other Unixes, strtok() has been deprecated in favor of strsep() for this very reason. here's a quote from the FreeBSD manual page for strsep(): HISTORY The strsep() function is intended as a replacement for the strtok() function. While the strtok() function should be preferred for portability reasons (it conforms to ISO/IEC 9899:1990 (``ISO C89'')) it is unable to handle empty fields, i.e. detect fields delimited by two adjacent delimiter characters, or to be used for more than a single string at a time. The strsep() function first appeared in 4.4BSD. My opinion is that functions like strtok and strsep don't save a lot of work. It's just as easy to write your own routine that copies characters until it finds a delimiter -- and that way you can make it easier to use from RPG. ------------------------------ _______________________________________________ This is the RPG programming on the AS400 / iSeries (RPG400-L) mailing list To post a message email: RPG400-L@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/rpg400-l or email: RPG400-L-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/rpg400-l.
