Hi folks,

    A professor here at UNO is having a problem with a DCL command file. He's
trying to loop through command-line parameters to a DCL procedure, by using
(what to call it?)  indirect evaluation, I guess. Anyways, here's a sample:

		$ p2 := "filename"		!Just for example
		$ count = 2
		$ temp := &p'count'
		$ t1 = temp
		$ show symbol t1

This yields the following:

		T1 = "&P2"

When what it /should/ do is assign the string "filename" to T1. Any
suggestions? DEC used an example very similar in the DCL Concepts Manual,
I believe, but it works. Any ideas what's wrong?  I've tried lots of combin-
ations of ":=" and "=" to no avail... Any help would be appreciated.
Please answer directly, as I'm not subscribed yet.

    By the way, the following works:

		$ temp = "p" + "''count'"
		$ t1 = 'temp'
		$ show symbol t1

but it seems like a kludge, and the "&" trick is supposed to work.
