It is possible to read the state of the flags with basic

[maeloterkim]

Hi 

In assembler there is a register that have the state of the flags zero, carry , etc

It is possible to read the state of the flags ONLY WITH BASIC (NOT ASSEMBLER) or the state of the carry flag, zero flag etc

No, you need to use assembler (in fact it's difficult even in assembler to read the entire flag without changing them). You can get them for example:

Code:

DIM flags as Ubyte

#define save_flags \
    ASM \
    push af \
    pop hl \
    ld a, l \
    ld (._flags), a \
    END ASM

REM Now you can save flags at any moment with this macro
...
LET a = 5: save_flags: PRINT "Flags: "; flags

You can also create a function if you feel more comfortable, but will require also assembler, and I'm not sure if flags will be altered when jumping
into the function:

Code:

function fastcall get_flags as Ubyte
  ASM
  push af
  pop hl
  ld a, l
  END ASM
end function

PRINT "Flags: "; get_flags

Perhaps you might find this useful??
