Harry,

I don't know about the first thing you're asking about, but I do remember several years back when first installing U2 and running into some problems, Robert cautioning me against using to call U2. Being that he (and Carl) made the whole thing up, I obeyed, without knowing exactly what the problem(s) might be. Caveat Hacker.

As for the second, why not use the CDD U2 routine? Add all the directory targets you want to registry, then, on the command line, CDD 'anywhere' and you're there. Too much typing? Not all that you want to accomplish? Okay, plug away.

I'm interested in using the ENTER key to execute both native Xy4 commands and U2 frames. I see that PrsExe50 is somewhat along these lines. But it seems to require:

1. beginning the U2 frame calls with a period--e.g.:
.lh
to do loadhigh.

2. Having stored something in SG 50.

I'm assigning to ENTER, in the keyboard file, a call to this new frame:

{{5ENTER}}
==0>BX es 1Q2 XC>JM 2.PrsCMlineQ2

--where is the little musical note for a textual carriage-return line-feed.

It seems to work nicely, with one anomaly: on a blank command line, hitting the ENTER key calls the U2 help file and tries to fetch ENTER. I can live with that.

Adding a "BX es 0Q2" after the first doesn't seem to make any difference. I guess exiting the frame does that automatically, as does exiting a program (in Xy4)?

A further tweak I'd like is for 5ENTER, when it fails to find either a native command or a U2 frame, to call my Change Directory frame. That frame takes certain command line arguments to change directories without my having to enter anything on the command line other than an abbreviation for the directory. E.g., with just the letter R on my command line, hitting the key now assigned to that frame changes to the Root directory--i.e., does "CD \". But that requires using a key different from ENTER to call my frame. To use the new 5ENTER frame to do that, I'd have to test whether or not U2 has failed to otherwise execute, and I don't know how to do that. Testing with didn't work.

Thanks for any help. I hope this has been clear.
