directory

Identifies where the client should look for the ADE r-code.

You can have different versions of ADE r-code on the same machine at the same time. As a result, you need a way to specify the ADE r-code directory to the client so that the client can add this directory and all of the procedure libraries contained in the directory to the PROPATH. The -baseADE startup parameter lets you specify the location of the ADE r-code directory.

At session startup, OpenEdge automatically adds $DLC/gui (or $DLC/tty for character mode clients) and all procedure libraries in $DLC/gui (or $DLC/tty) to PROPATH.

When you specify -baseADE, the $DLC/gui (or $DLC/tty) directory and the procedure libraries in $DLC/gui (or $DLC/tty) are not added to PROPATH. Instead, the directory specified using the -baseADE startup parameter is added to PROPATH followed by all of the procedure libraries in the directory. For example, if you use -baseADE to specify the following:

-baseADE c:\maint\gui

And c:\maint\gui contains the following procedure libraries: adecomm.pl, adeuib.pl, and protools.pl.

The PROPATH looks like the following:

...,c:\maint\gui,c:\maint\gui\adecomm.pl,c:\maint\gui\adeuib.pl,c:\maint\gui \protools.pl,...

If $DLC/gui (or $DLC/tty) or any of the procedure libraries from the directory already are part of PROPATH (environment variable, .ini file, or registry setting), OpenEdge does not remove them.

OpenEdge allows you to specify an empty string for <directory>, -baseADE "". In this situation, OpenEdge does not add $DLC/gui (or $DLC/tty) or the procedure libraries in $DLC/gui (or $DLC/tty) to PROPATH.

You also can specify the ADE R-code Location with the BASE-ADE attribute of the SESSION system handle. For more information about this SESSION attribute, see the OpenEdge Development: Progress 4GL Reference .
