Is there a way to scan for hidden varibles? I often try the miscellaneous postings here without carefully inspecting the sysevals used. I guess it is concievable that there are a few gremlins lurking about. Dan -- Daniel C. Flatin 1-919-684-8279 Duke University Dept. of Physics dcf@phy.duke.edu Durham, N.C. 27706

Dan Flatin asks if there is a way to scan for hidden variables. If all you want to do is see if there are any, you can use Rick Grevelle's HACKIT library to determine this easily: Put the name of the directory on the stack, then use this: DUP EVAL RCLDR ->DIR UPDIR SWAP RCL == If this yields 1, then there are no hidden variables; if this yields 0, then there ARE hidden variables. Once that's done, you can easily find out what they are by entering the directory, doing a VARS (that'll give the visible vars), then unhiding everything, and doing a VARS again, and taking the SUB of this list which shows just the newly obtained vars (they'd be the previously hidden ones). I hope that makes sense. -- Joe Horn --
