Hi, Paul
Take a look at:
Installing Clipper 5.x on Win/XP
thread288-942760
Hwvr instead of editing config.nt or autoexec.nt, in XP:
-right click on My Computer
-click on Advanced tab
-click on Environment Variables button
-add clipper env variable to system or user environment
(I use F100;E0)
-add path to clipper5\bin to the path variable
-add path to clipper5\lib to the lib variable (or create if not already there)
Then any dos window you open will be configured for clipper.
The above thread also gives references for handling the problem of CPU being maxed out by clipper progs under XP.
