Thanks but I meant that[EAX+EBX+ECX] EQTYPE [EAX+EBX] will return true, but I want to split them, not asking how to get the value of EAX+EBX+ECX or 12*EAX

I accidentally deleted the post, sorry about this.
Code: ;LEA EAX, [12*EAX] ;COMPILE ERROR lea eax, [eax+2*eax] shl eax, 2 |

Sure, if that is what you want to do. But until you explain your goal we can only keep guessing about what you want.

I want to calculate the address with some commands when it is not possible to use a SIB to find it

You didn't mention the input set restrictions so unless you have a some restricted input set then a full parser will likely be needed.

It is worth noting that fasm g offers much better facilities in this regard, since it allows to extract the coefficients and variables of such linear polynomial and this is how it processes the SIB expressions in the 80386 macros.
