asm/endasm DEFB not accepting 0xFE or FEh instead of 254 - nitrofurano - 2011-10-06

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:
guest@macbook_mint1 /mnt/sda4/trabalhos/programacao/8bit/zxspectrum/ftpupload/zxspectrumstuff_20111001/borielzxbasiccompiler/snippets $ zxb.py -t -B -a asm.bas Generating LALR tables WARNING: Token 'BIN' defined, but not used WARNING: There is 1 unused token Generating LALR tables WARNING: Token 'UMINUS' defined, but not used WARNING: There is 1 unused token asm.bas:2: Error: Syntax error.

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

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.

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
