The code named by you only works with a very old Bourne Shell that can be retrieved from the server of Geoff Collyer. If you are interested in the recent Bourne Shell (SVr4 + Solaris changes), you better use my Bourne Shell sources that can be found inside the schily-tools: http://sourceforge.net/projects/schilytools/files/ The code from above will not work in a recent Bourne Shell without changes in both, Geoff Collyer's stak.c and the rest of the Bourne Shell.
