Hi
Would it be possible to predefine "ShortString" in GPC? (as "String [255]"). I appreciate that GPC doesn't yet have longstrings so this may seem pointless - but I can't see any harm in having ShortString already defined (at least, in Delphi mode).
Thanks.

Does Delphi has the `ShortString' identifier? (I suppose to get a short string, independent of the `{$H+/-}' setting which seems reasonable.) If so, the following patch should do it:

No, I meant long strings (AnsiString). GPC already (in a manner of speaking) has short strings, since "String" is treated as a string of 255 chars (at least, that is what the GPC warnings say).

Yes, it has had it for a long time (since Delphi 2.0 in 1996) ...

Indeed.

Will try it over the weekend. Thanks.

No, I meant long strings (AnsiString).
GPC has long strings, up to length 2^31 on 32 bit systems, and 2^63 on 64 bit systems, according to ANSI/ISO Pascal.
So what you mean is the particular string implementation of Delphi which it misnames `AnsiString' (since AFAIK no ANSI standard describes these strings, certainly not the ANSI Pascal standards).
GPC already (in a manner of speaking) has short strings, since "String" is treated as a string of 255 chars (at least, that is what the GPC warnings say).
Of course, GPC allows strings of capacity 255 (or any other smaller capacity than its maximum). So what I meant is the particular string implementation of UCSD and Borland Pascal.
