RE: diff btw Procedures and Routines

[Jim Langston <jlangston@xxxxxxxxxxx>]

I know for a fact that a procedure can see file variables in the program.

But I thought that a procedure could not see local variables in the program.  
Is this not true?  By local variables I mean ones created in the D specs of the 
main program.

Jim,

This isn't exactly true, a procdure that is defined in the same module as
the main program can see all the variables in the main program.  In fact,
files (and thus their fields) cannot be defined in a procedure but they can
be used there.
