See the following example:
The Pascal procedure, SimVal.p. t, f, c, i, r, and s are value parameters.
procedure simval_(t, f: boolean; c: char; i: integer;
r: real; s: integer16; var reply: integer);
begin
reply := 0;
{If nth arg is ok, set nth octal digit to one. } if t then
reply := reply + 1; if not f then
reply := reply + 8; if c = 'z' then
reply := reply + 64; if i = 9 then
reply := reply + 512; if r = 9.9 then
reply := reply + 4096; if s = 9 then
reply := reply + 32768
end; { simval_ }
