Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

 PROISAMD.EXE contains all ISAM routines needed to run most database
 programs. Similarly, PROISAM.EXE contains ISAM routines with the following
 exceptions:
 • Excludes the "data dictionary" statements CREATEINDEX, DELETEINDEX, and
   DELETETABLE
 • Contains a restricted version of the OPEN statement that opens a database
   or table, but will not create it if it does not already exist
