GCBASIC Code

Revised Table handler for OX to &H as 0X caused major issue with Linux build of the compiler.

Improve If statement error checking: An If without an End If now permits further compilation of If statements in that subroutine to detect further errors.

Fix for compiler bug: Setting the return value of a function by using it as a subroutine parameter did not work

Two compiler changes:
- Fixed bug when If statement condition involved testing two bits and a logic operator
- Added error message for variable names that start with a number - this usually either a sign of a deeper problem, or a name choice that will cause problems with MPASM.

Fix for two compiler bugs:
- If a subroutine call had a parameter value with brackets, anything after brackets would be ignored
- Brackets with spaces between them after a subroutine declaration caused the subroutine to be ignored

Fixes for two compiler bugs:
- #option explicit was not recognised when combined with other #options
- Empty Do loops were compiled incorrectly and would never exit, unless /K:A switch used to preserve input code in assembly

Fixed parsing errors in GCGB, related to comments after If statements, comments after sub/function definitions, and assignment operations with no spaces before/after the = sign

Updated device 10f320.dat

Fix for bug in select statement introduced in commit 614. The presence of a second Select block in a subroutine would cause a null pointer exception.

Improvements to Select command:
- Case statements can now use To operator (ie Case 3 To 5)
- Experimental jump table mode added. Slightly reduces program size in some situations, but not thoroughly tested. For now, enable by creating a constant called SELECT_USE_JUMP_TABLES. Will become default in future.
