Re: PL/I question

There are no troublesome characters. If it's CHARZ then a '00'X marks the end of the string, as in C. Otherwise there is an explicit length that is the same regardless of what characters are in the string. The length may be determined at, e.g. compile time, block entry, or may be dynamic

I think you could probably learn "how" to make your product on the LE edition and if things start working out for you and you think you might have a viable product, you could then switch to the personal edition. I don't think you are locked into anything by starting with the LE edition. Many

#1 yes, of course, cutting Version 0.1 is just the start of being in the software business. #2, there would seem to me to be a whole continuum of cases (FWIW). What if I have an idea for a commercial product. I use an LE to develop a prototype and test out my ideas. When I have the prototype

Re: PL/I question

Interesting. Thanks. I ask because many modern languages owe enough to C, or use libraries that do, that it's become a working assumption that null, backslash and the like will probably break something. I wrote a crude x86 compiler once, just to have a compiled language for my own use that

No, APL was neither Polish nor Reverse Polish; it was infix. However, there was no operator precedence. BTW, be careful of the word "operator", because in APL it has a special meaning (see ) that would probably be

Between PL/I (F) Version 4 and 5, a fix broke the optimization of unaligned bit strings, V5 generated calls to library routines for code that V4 would translate into inline TM and such. The "Optimizing" compiler continued to generate library calls for that code, making analysis of SMF data
