ctc-spf-users: Users of CTC's SPF products

This is an unofficial list (ie not run by Command Technology Corporation) set up to allow users of CTC's various SPF products to help each other.

CTC's SPF products run on Windows systems and provide varying levels of emulation of the IBM mainframe file handling, file browsing, file editing and general application platform software known originally as System Product Facility (SPF) and latterly as Interactive System Product facility (ISPF).
