I was looking some codes and I saw a thing like this: 



error db 13, 10,"Error on initialization.", 13, 10, 0

error_init equ $-error


What does this "$-..." mean? Thanks

the "current" location, so $-error would return the length of error

Funny that MS is using extensively the symbol $ :)

Many assembler's "current address symbol" is the "$" , not microsoft MASM only.

$ - Target = Current Address - Target
