I have written two presets:
/play/pbm/play.php?game%3DBreakthrough%26settings%3DBreakthrough
/play/pbm/play.php?game%3DSquirrel+Chess%26settings%3DSquirrelChess1
May I ask some questions about Game Courier / GAME code:
1. I observe that I can't enter comments starting with '//' in the
Pre-Game part. I wrote:
// comment
setsystem maxmove 2;
...
And I receive an error message:
Syntax Error on line 0
// comment
setsystem maxmove 2 is not a valid expression, because // is not a
recognized piece, coordinate, command, or subroutine.
Why is this?
2. What happens if I edit and save a preset if there are already players
using it, e.g. when I remove a bug or add notification for mate /
stalemate. Can this cause problems?
3. What happens if an operator needs more operands than are on the stack,
or if there are two or more values left on the stack after evaluating an
expression, or if an operator is given an operand with a senseless type,
e.g.:
set ep false;
...
if equal where #ep 0 1 a3;
...
endif;
Are there rules how such cases are handled, or does the program behave in
an undefined way?
4. am I right that a board position (like 'a4') is of type 'string',
and also a piece type like 'n' or 'K'? Or are these special types on
their own?
