Small brackets-parsing glitch (*solved*) - LTee - 02-23-2011
Messing around with some of my other code over lunchtime with the latest beta (2100), I discovered a small error when parsing brackets.
Take a look at this code:
Code:
DIM test(10, 10) as UBYTE
DIM x as UBYTE
DIM y as UBYTE
x = 5
y = 5
PRINT test(x - 1, y)
PRINT test((x - 1), y)
PRINT test(x, y - 1)
PRINT test(x, (y - 1))The final PRINT statement will not compile unless you remove the brackets from around the (y - 1). Strangely, the brackets seem to be okay if we're dealing with the first dimension of the array (so it's okay to have 'x - 1' in brackets), just not for the second. :-)

Whoops, I forgot to mention that the compile error is this:
Code:
Error: syntax error. Unexpected token '(' [LLP]Re: Small brackets-parsing glitch - boriel - 02-23-2011

hock: This is going to be the new preprocessor (what a nightmare!) :mrgreen:Try filtering it throug zxbpp:

Oops! Sorry! :-D

Ok, seems to be fixed.
As always, download 1.2.7-r2103 from here: <!-- m --><a class="postlink" href="http://www.boriel.com/wiki/en/index.php/ZX_BASIC:Archive">http://www.boriel.com/wiki/en/index.php ... IC:Archive</a><!-- m -->

That seems to have done the trick, boriel - code's compiling and running normally now!
Many thanks, as usual!
