There are some real mis-communications and conceptions here..

First of all, the include file macros can be passed positional parameters
or named parameters, and are a very fast way to work.  If you must use
subroutines, then you can run lots of small .p procedures to do what you
want and configure the memory buffers to handle them well.  This is true
for both Version 3.x and 4.x, and we now use Version 5.x.

As for 64K size limit, that is true, but for someone who wants to write with
sub-routines, you can call any number of sub-procedures, each one of which
can be up to 64K compiled size.  Remember that is the compiled size, as
the source can be larger, especially when using the include files.  All
variables can be defined as Global, Shared, or Private... in fact the default
is private local.  I think perhaps Steve gave up a little too soon.  If
there is anything that is idio-syncratic about Progress, it is the use of
Scoping and Frames... But you learn to love it.

Also with version 5.x, you can mix both Progress 4GL code and SQL statements
in the same code, even use Progress Verb modifiers to SQL statements.  It
supports standard Ansi SQL.  This is native mode, not just an interface.

There is a Progress users BBS available at 215,446,4035 that is NOT run
by Progress, but by Progress users.  Give it a call if you have such
