- duplicate diskio for cx16 (get rid of cx16diskio, just copy diskio and tweak everything) + documentation
- get f_seek_w working like in the BASIC program - this needs the changes to diskio.f_open to use suffixes ,p,m
- attempt to fix the expression codegen bug with reused temp vars (github #89)
- AstIdentifiersChecker: can a subroutine really not have the same name as its enclosing block? 64tass problem? - AstIdentifiersChecker: can a subroutine really not have the same name as its enclosing block? 64tass problem?
- attempt to fix the expression codegen bug with reused temp vars (github #89)
- 6502 codegen: make it possible to use cpu opcodes such as 'nop' as variable names by prefixing all asm vars with something such as ``p8v_``? Or not worth it (most 3 letter opcodes as variables are nonsensical anyway) - 6502 codegen: make it possible to use cpu opcodes such as 'nop' as variable names by prefixing all asm vars with something such as ``p8v_``?

then we can get rid of the instruction lists in the machinedefinitions as well. This is already no problem at all in the IR codegen. then we can get rid of the instruction lists in the machinedefinitions as well. This is already no problem at all in the IR codegen.
- create BSS section in output program and put StStaticVariables in there with bss=true. Don't forget to add init code to zero out everything that was put in bss. If array in bss->only zero ONCE! So requires self-modifying code - create BSS section in output program and put StStaticVariables in there with bss=true. Don't forget to add init code to zero out everything that was put in bss.
