I don't know specifically about FreeCOM, but I know in some versions of DOS an environment variable can't contain an equals sign. For example, in some DOS versions you can't do this while in others you can: SET ParameterList=Var1=1,Var2=2 This has caused me some grief in the past when I try to allow the user to enter option parameters either from the command-line or from an environment variable. For example, if the program I'm trying to run is called PROGRAM I allow the user to set an environment variable named PROGRAM that contains the "default" command-line parameters: SET PROGRAM=Option1=Yes, Option2=No I want that to work the same way as if the user had done this: PROGRAM Option1=Yes, Option2=No Sometimes it works and sometimes it doesn't, depending on which version of DOS I am using. And I'm not even sure it is consistent across all different DOS versions from the same manufacturer. BTW, the way I get around this problem is to allow the user to either enter an equals (=) or a colon (:) as the separator character and explain the situation in the documentation.. The reason I bring this up is that in a recent post there was some discussion over whether or not FreeDOS should fix all the bugs in MS-DOS (essentially, improving MS-DOS) or duplicate the bugs, and the consensus seemed to be to duplicate the bugs. I don't know if allowing an equals sign in an environment variable would be considered a bug or a feature, but I would classify it as a bug, and I don't remember specifically how MS-DOS handles it. _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
