Rather to my surprise, so far ALL the answers have missed the poont of my original question which I THOUGHT I'd made clear, but obviously I didn't :-) I am well aware of the *PROGRAM* path feature which I gave an example of. Everyone referred to that, which I am aware of, and which is not useful for solving the problem, alas. AFAICR there is also a much more rarely used ***DATA*** path feature available somewhere in the dark arcanery of the MSDOS world. As for "what's wrong with using ..." - I have mo idea - but it doesn't work :-) ie the more normal DOS tricks fail. What I am looking for is what I (thought I) said I was looking for - a command that allow sprograms referencing data in what they actually think is their "current directory" to be actually accessing it in 1 or more directories OTHER THAN the current director . eg Say the command I want was DATAPATH .... _______________ DATAPATH C:\FRED C: CD \JIM DIR ALLAN ______________ would list all files named ALLAN BOTH in C:\JIM and ALSO in C:\FRED ie C:\JIM\ALLAN & C:\FRED\ALLAN A truly dangerous facility :-) But, sometime suseful.
