Hi, how can I create procedure with undefined number of parrameters. Writeln is example of what I am looking for for example procedure add(a,b,c,.... var result) Pianoman
Declare a Function or a procedure as MyProc(P1: String; Args: Array of Const);
And as Michael Van Canneyt said, you can use as many parameters. But dont forget to compile it with -S2 option.
Like C, you must provide some method to distinguish between different data types within the first parameter itself, and access the rest using: Args[ParameterNumber].vChar for Char Args[ParameterNumber].vString for string and Args[ParameterNumber].vInteger for integer data types.
Actually, quite the contrary: Unlike C "..." construct, you *don't* have to encode in 1st parameter exact types of the variable parameters. Args is just an array of TVarRec records:
- you can gen their Length by High(Args),
- and you can check their types at runtime by looking at Args[ParameterNumber].vType
