Hello, everybody!
I noticed a lot of confusion about Integer types in GNU Pascal.
As I wrote in "info -f gpc -n Integer", these are
bits signed unsigned C equivalent
8 ByteInt Byte [unsigned|signed] char 16 ShortInt ShortWord [unsigned] short 32 Integer Word [unsigned] int == long 64 LongInt LongWord [unsigned] long long
(BTW: The number of bits is the same on all platforms, isn't it?)
I was told more than once that `Word' should have 16 bits (like in Borland Pascal). I made it 32 bits because this is the "natural" size on a 32-bit system (like GPC), and it has the same size as `Integer' (like in Borland Pascal;-).
AFAIK, a "word" is defined to be the "natural" unit of the computer, but maybe this definition has changed since I have learned it. If the definition of a word is indeed "16 bits" now, I should change GPC's behaviour. In this case I would appreciate suggestions how to rename all GPC Integer types above (which I wouldn't like to do because I find the above quite consistent).
Greetings,
Peter

Hallo peter@agnes.dida.physik.uni-essen.de ... Du hast am 13.06.97 eine Nachricht zum Thema `Word' data type geschrieben - Selbst schuld wenn ich jetzt auch schreibe.

(there's a --borland-pascal switch?) then it's the same as BP; 8bit shortint byte 16bit integer word 32bit longint (longword) + 64bit (hugeint) (hugeword) ? advantage: BP programms can be compiled more identically.

I like the above, too - it's nearly the same as it was defined here before GPC learned about the types... PG>Greetings, PG> Peter
