hi. i'm programming in turbo 5.0 and was wondering if it is possible/efficient
to run other files from my program. here's the scenario: i have a large piece
of code that will only be used the first time a new user runs the program.
can i separate it out and only call it when needed to save space and memory?
include {$i } doesn't seem to be what i want; i'm talking run-this, exit-and-
run-this-other-one, exit-second-and-back-to-first.
any help := greatly appreciated;nemossan@uitec.ac.jp (Sakurao NEMOTO) (03/20/91)

For this purpose, Overlay is used. Please see your manual. Overlays can be used in turbo-3,5,5.5 or 6 (I mean you cannot use in Turbo-4). nemossan@uitec.ac.jp

It appears that pages 264 and 265 of the copy of the TurboPascal Reference Guide you received when you purchased the compiler are missing? You should perhaps complain to Borland about this oversight :-)

One or both of overlays or procedure Exec should suit your requirements. Both are available in TPas 5.0 and discussed in the manuals. Read the references to those features, and inquire again if you still have (specific) questions. You might mention what the memory requirements of the one-time and every-type programs might be, and what you want to do during the one-time program (write a config file, send the user's VISA card, modify an .EXE file, etc.).
