UniVerse has the compiler option "-X" (same as "-XREF") that builds a cross
reference of all variables, includes, subroutine labels, etc. It identifies
the line(s) it is assigned a value, and the lines that reference it. The key
is the program id and is stored in a file with a .L suffix (so if you compile a
program in the BP file, it would be stored in the BP.L file).
The "-L" ("-LIST") resolves all the includes and places it in the .L file. The
key is the program id.

Subject: Re: [U2] local variables
I think it's already been mentioned, but I'll repeat. Both universe and unidata
have the ability to create a cross-reference listing of a program. unidata's is
particularly nice and shows every variable, including what lines the variable
is defined and used on.
but it would still be nicer to have local variables.
You can do this in mvbase. Instead of external functions defined with DEFFUN,
mvbase has internal functions with local variables.
You can also do this in Caché.
