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documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

Use Procedure Step (or press F10) to run a single statement
in your program and to run a procedure call and the
procedure it calls as a single statement.
 
Procedure Step, like the Step command, allows you to move
through the execution of a program one step at a time, but
it saves you from stepping through procedures that you
know work correctly.
