ASM help please

[labrat31]

I am new to programming I have only assembled and tested about 5 codes this is my biggest second biggest was computer serial to 8051 to p2.
trying to get this i2c program I found to assemble so I can simulate it and go throu it step by step to see how it works but I cant assemble, the 2 problems are:

; Data storage locations
BitCnt DATA 8h ;Bit counter for I2C routines.. . . . . . . error illegal opcode
NoAck BIT Flags.0 ;I2C no acknowledge flag.. . . . . . . . . error illegal Value
For more of an explanation see .asm

thank you
