Please put the contents in hex format so it can be appropriately evaluated. That is to say if the ebcidic is SCOTT1, the hex would be x'E2C3D6E3E3F100'. There is insufficient information to provide an accurate answer. The memset shown above is not needed. strcpy copies to the dest from the source starting at the left most byte of the dest until a binary zero is encountered in the source field. The binary zero in the source field is copied to the destination field. This can (and does) cause buffer overflow if not properly managed. > > Otherwise strcmp fails, where xxxxx is the parameter string > > Scott ford > www.identityforge.com > > On Sep 4, 2012, at 1:05 PM, retired mainframer <retired-mainfra...@q.com> > wrote: > > > The construct > > char x[3] = "ABC"; > > will legally initialize an array of char without adding the '\0'.
