Function Return Values
Function return values match types in the same manner as with parameters,
and they pass in much the same way. See “Variable Parameters” on page 94.
The following example shows how to pass simple types.
The Pascal main program,
SimValMain.p
program SimVal(output);
var
t: boolean := true;
f: boolean := false;
c: char := 'z';
si: integer16 := 9;
i: integer := 9;
sr: shortreal := 9.9;
r: double := 9.9;
args: integer;
procedure SimVal(
t, f: boolean;
c: char;
si: integer16;
i: integer;
sr: shortreal;
r: double;
var Reply: integer);
external c;
begin
SimVal(t, f, c, si, i, sr, r, args);
writeln(' args = ', args :6 oct);
end. { SimVal }
The commands to compile and
execute
SimVal.c and
SimValMain.p
