I have need to use the CLI routines recursively. What I want to do is call CLI$Parse with one string, grunge through things a bit, then call CLI$Parse with a second string, grunge through that a while, and then revert back to the original string. The idea of re-parsing the original string does occur to me but I don't think that's feasible since that does not preserve the exact state of the CLI routines (eg. scanning lists). One reason for this is that I have a list each item of which can be a logical name that can expand to its own list. I know I can write my own scanner but it would have to do all the things that the CLI routines do so well. Is there any way to preserve the state of the CLI routines or any way to have several strings open at once and switch between them? dorl@vms.macc.wisc.edu dorl@wiscmacc.bitnet

>...I have a list each item of which can be >a logical name that can expand to its own list. ... I may be mistaken, but if you specify a command line of $ command Logical-1, Logical-2, ... Logical-n then, before you read anything with CLI$whatever, these logicals are converted into their actual meanings. In other words, the first thing read is the first value in the list represented by Logical-1, and so on. Again, I may be wrong, but my experience in general, is that you get actual values and not symbols through CLI$* function. Hope this helps (and is correct). +---------------------------------------------------------------------+ | Mark H.
