Hi R'Shmuel AMV"SH,
Like ALGOL and Pascal?
Regards,
David

Subject: 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 absolutely, definitely handled any byte value exactly the
same. It was supposed to be terse like C, but work more like PL/I.
Oh, and I can't remember how far I got, but I started by abolishing = for
assignment. It was implicit in the syntax and = was only used for
comparison. I was young and foolish :-)

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 (VARYING).

Subject: Re: PL/I question
Related: how does LE handle strings with embedded troublesome bytes such as
x'00'? And is it different between PL/I and C?
I am reading the PL/I Programming Guide, but it takes but I'm hoping there
is an easy off-the-cuff answer.
Most of my PL/I experience was before LE, you see.
