Quite embarrassing for someone programming in Pascal for 41 years, who should know better as to where to put a comma and where to put a semicolon... :-[ Just picture me slapping myself hard for the next hour or two... :-!

Well, no, the error messages just state "expected this, found that",
without actually giving a REAL hint...
The declaration would be something like this
Type tStateRecord = Record
StateAbbrev : String [4];
StateName : String [40];
InLower48: Boolean;
end;
tStateArray = Array [1..MaxNoStates] of tStateRecord;
Var {or Const, so it's initialized only once}
States : tStateArray = ( (StateAbbrev : 'AL', StateName :
'Alabama', InLower48:TRUE),
(StateAbbrev : 'AK',
StateName : 'Alaska', InLower48:FALSE),
...
);
Various versions of parenthesis just vary the error message, either the
above mentioned "expected this, found that" or "filed xyz not initialize"...

This comes from a working program, and the compiler didn't complain, so
I assume it is the correct syntax (the added comments are unnecessary,
of course):
type
Tentry = record
bf: array [0..3] of Integer;
sq: array [0..3] of Integer;
ls: array [0..3] of Integer;
ins:array [0..3] of Integer;
end;

{ N=0 }
{ bf }(bf: (0,0,0,0);
{ sq }sq: (1,2,0,0);
{ ls }ls: (0,3,0,0);
{ ins}ins:(1,0,0,0)),
{ N=1 }
{ bf }(bf: (0,0,0,0);
{ sq }sq: (1,1,0,0);
{ ls }ls: (3,0,0,0);
{ ins}ins:(1,0,0,0)),
{ N=2 }
{ bf }(bf: (0,0,0,0);
{ sq }sq: (2,0,0,0);
{ ls }ls: (3,0,0,0);

{ bf }(bf: (0,0,0,0);
{ sq }sq: (3,0,0,0);
{ ls }ls: (3,0,0,0);
{ ins}ins:(1,0,0,0)));
I hope that it helps,

[fpc-pascal] Correct syntax for initialized constants/variables
I try to include some initialized constants/variables in an application of mine, but somehow stumbled upon a stupid little problem that I can't figure out myself after nights on the computer. I see in the reference docs (section 4.4) examples for arrays and examples for records, but in my case, I would need to properly define an array of records. Any hint/example for the proper syntax in that case would be deeply appreciated, it's probably something simple that I am missing, tia, Ralf --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
