SHIFT bug (*solved*)

[einar]

Try this:

Code:

DIM a AS UBYTE = 3
DIM b AS UBYTE = 2

PRINT a << (3-b)

Attempting to compile this program using latest ZX BASIC version 1.4.0s1953 will produce this error:

Code:

Error: Undefined label '__LABEL0'

It will only compile correctly if you disable compiler optimizations using "-O 1".

Previous ZX BASIC version 1.4.0s1935 was able to compile this correctly at any optimization level.

Another bug due to the update after 1935.
Can you download ZX BASIC 1.4.0s1964 and test it, please? :roll:

It works now, thank you!
