To save a newly created or modified program, select one of the three options from the
File menu. The Save all command saves all the current program windows to the
associated files. The Save command saves the file to which the front window
belongs; this takes effect only if the window is a program window. The Save as...
command allows to save the file to which the front window belongs under a different name
by means of a dialog window; the front window can be either text or program in this
case.
NOTE : It is advisable to save the program every so often after changes
have been made to it. This is a safety measure to ensure that modified text will not be
lost in case re-booting is necessary during the MacProlog32 session. It is also advisable
to keep a second copy of your data disk in case of catastrophes.
