Re: [EXTERNAL] RE: the cycle that never ends

"... Why not instead put all the time and effort that went into RPG IV into turning the OPM subset PL/I compiler into an ILE-based full implementation of the language?"

We looked at updating PL/I - but it would never have been instead of RPG IV - that would have been ridiculous and we would justifiably have been lynched by RPGers.

It was impossible/impractical to do PL/I for many reasons including the fact that there was no ILE oriented PL/MI compiler and no re-usable PL/I code base written in C or C++ that could be used. That meant a total rewrite would have been required.

Given the minuscule number of PL/I users and the fact that it was unlikely to attract many (if any) additional users it would have been a total waste of time and money.

Without The Cycle, what (other than scatter-gather I/O, which is of far more questionable value than The Cycle is) is left to distinguish RPG from any other HLL, other than a really odd syntax?

Without The Cycle, why bother having RPG at all? Why not instead put all the time and effort that went into RPG IV into turning the OPM subset PL/I compiler into an ILE-based full implementation of the language?
