Subject: Re: PL/I compiler

As of 1988 the VAX VMS PL/I compiler was not a full implementation of the
language as defined by IBM.

I had a 65,000 line PL/I program for the IBM 3090 that required
15,000 lines of changes just to get it to compile under VAX PL/I.
Unfortunately, the program also required a CODASYL compliant database
which was not available for the VAX at our site at that time.

I do not remember the exact problems but they were subtle uses of 
the language. 

The only company I'm aware of that has a PL/I compiler that may be
of any value is LPI (I do not have the address). Unfortunately, I
think their compilers only run under UNIX and maybe a handful of
other operating systems (But not MESSDOS).

DR's PL/I compiler is garbage. All "Subset G" PL/I compilers are going
to be worthless if you are transferring from an IBM mainframe compiler.
