help with decimal points

[treefort]

Hi all,

I am trying to figure out the difference between decfsz .13 and decfsz 13.

This is the code I am looking at:

movlw .13 ; Delay another 10mS plus whatever was above
movwf Delay2
TenmSdelay:
decfsz Delay1,f ; Delay1 is currently at 255
goto TenmSdelay
decfsz Delay2,f
goto TenmSdelay

Is there a difference if it was movlw 13?

Thanks,

Trevor

Putting a dot in front tells the assembler that it should treat the number as decimal. MPASM defaults to hexadecimal and so without the dot it will be the same as movlw 0x13 which is 19 decimal. You can also do movlw d'13'.

Mike.
