Overview
This readchar(f) function will read a character from a file with handle f. The file handle maintains its position in the file, so after a call to read char the position pointer will be incremented.
Example
#include <io>
function void main() {
var f:=open("hello.txt","r");
var u:=readchar(f);
close(f);
};
Since: Version 0.41b
