shell expansion in strings ?

[John Darrington]

I wonder if it would be a good idea to allow strings to be shell
expanded.   For example, it would be convenient to be able to write:

GET FILE='$HOME/foo.sav'.

instead of 

GET FILE='/home/john/foo.sav'.


On the other hand, it makes it slightly incompatible.  Also strings
which represent data should probably not be expanded, which would mean
that somehow the syntax parser would have to be able to distinguish
between the two types of string.

Also, would there be any conflict between :

COMPUTE x = $CASENUM.

and

COMPUTE x = '$CASENUM'.


Just some thoughts ...
