Weird DEFB bug (*solved*) - einar - 2015-02-22
Try running this program:
Code:
GO TO 10
sample:
asm
defb "A(B)CD"
end asm
10 DIM a,i AS UBYTE
FOR i = 0 TO 5
LET a=PEEK(@sample+i)
PRINT a;" '";CHR$(a);"'"
NEXT iIt was supposed to produce this output:
Code:
65 'A'
40 '('
66 'B'
41 ')'
67 'C'
68 'D'However it will produce this output instead:
Code:
65 'A'
32 ' '
40 '('
66 'B'
41 ')'
67 'C'Apparently this extra space (code 32) mysteriously appears whenever there's parenthesis inside a defb string.
Tested using latest version 1.4.0s1902. This problem always happens regardless of optimization level for compilation.

Confirmed bug.
hock: And I'm puzzled, because I though it was in the preprocessor. It is not.

It was a bug in an bizarre code in the optimizer I need to refact (as always).
Please, can you download ZX BASIC 1.4.0-r1912 and tell me if it works ok? :roll:
