Huh? Works for me with FPC3.2.2-32Bit - Laz2.2.2-32Bit (Sorry, should have mentioned it?)

Arrgghh..... Mea Culpa....missed that it's about a CONSTANT...

Yeah, your solution works, since it gets resolved during compile-time, not runtime

The rest of the elements are nulls.

Please note that a array of Char can be considered a special case, because the compiler will essentially initialize it like a NUL-terminated string. For other array types this wouldn't even work, there you need to really provide an array declaration.

If we would have more ISO Extended Pascal support already then there'd be a solution for you:

Code: Pascal  [Select][+][-]
  1. type
  2.   TMyArr = array[0..8191] of Char;
  3. const
  4.   SPACE_ARRAY = TMyArr[otherwise ' '];

That would be very nice :)

Thank you for making it clear that, at least at this time, there is no simple/straightforward way to have the compiler initialize the constant as desired.

Of course you haven't. There aren't that many compilers supporting ISO Extended Pascal after all.

Well, I will ask Scott Franco. I understood - maybe from him - it was implemented in P5x.
In that case I probably already have it, unless it did not make it to the Pascal to  GNU C transpiler. (P5C).

Afaik p5 was mostly about ISO 7185, not extended pascal.

p5c seems to also only list 7185 level 1 as status: https://sourceforge.net/p/pascal-p5c/wiki/Home/

Prospero and GPC are the extended pascal's gotos afaik.

Marco it is P5x as a literal where the x means x, not a substitution char, but indicates extended pascal.
