I actually was not aware that there even was a command called findclose, and I never did it in Turbo Pascal.. it IS in there now, and I believe it was a discussion on this list that prompted me to add it. Anyway, just wanted to say, there are reasons to want to port Turbo Pascal code and then switch over to systutils, so having documentation that includes the differences between the versions would be helpful.
Turbo Pascal (for DOS) didn't have a FindClose function, as
"officially", this would not be necessary on DOS. On all other OS,
including Windows, for many, many years (I first stumbled about missing
"FindClose" call in OS/2 some time in the early '90s) and got used to
*alway**s* terminate a file search with it, even if it is in the case of
DOS just a dummy routine that just returns without doing nothing. Saves
a lot of headaches trying to find the source of apparent memory leaks in
larger applications that do a lot of of file searches...
