asm/endasm DEFB not accepting 0xFE or FEh instead of 254

hi!
i always had some idea that z80 assemblers accepts byte values in hexadecimal format, instead of only decimals - i'm i wrong, or is this zxbasic compiling missing this feature? (or can we suggest this feature?)

  Code:

NOTE: To remove these warnings, enter your zxb.py directory and type ./zxb.py to create the static cache. These warnings should not appear anymore.

  Code:

asm
DEFB 0,1,2,3,4,5,6,7
DEFB 00h,01h,02h,03h,04h,05h,06h,07h
DEFB 0xff,0xfe,0xfd,0xfc,0xfb,0xfa,0xf9,0xf8
end asm


The 0xNNN format is not allowed. Use $NNN format or NNNh format.
E.g.

  Code:

$C9 <-- Allowed
1Fh <-- Allowed
FFh <-- Error. "FFh" is an identifier. Prefix with "0"
0FFh <-- Ok. Now allowed.
0xC9 <-- Not allowed


thanks!
