Hi fine GPC hackers, please take a look at this foolish code, I, as a novice, have a little problem with pointers in Pascal ;-) (I wonder why I don't just keep using C:))
: type : PStrList = ^TStrList; : TStrList = record : Next : PStrList; : S : TString; : end; : : var : StringList : PStrList; : : procedure Foobar; : var : Str : PStrList = StringList; : begin : repeat : New(Str); : Readln(F (* : Text *), Str^.S); : if Length(Hdr^.S) = 0 then : break; : Str := Str^.Next; : until False; : end;
Due to the assignment of StringList to Str, at the end of Foobar I'd get StringList not to be the head of the list but the last element. How can I keep a pointer which always points to the first element? Maybe that's really easily done, but of course in Pascal it doesn't seem that it works like in C, and I'm out of manuals ;-)
TIA
Nicola
