Hi all, If there is another group specific to the GNU assembler, please let me know. On to the question. Does anyone know an equivalent code in assembler for intel's word 'struc'. As in: ****************************** 23: MAP_IO_S struc 24: ioc_select_reg db ?, ? #IOC select register 25: panel_ctrl_reg db ?, ? #panel control register 26: MMAP_IO_S ends ****************************** I did some searching and actually found a post that claimed that by placing .intel_syntax at teh top of the file, the file would compile using intel assembly syntax. The actual error message I am getting is line 23 Error: invalid character '_' in mnemonic Thanks, Yamin ---------------------------------------- This mail sent through www.mywaterloo.ca
