labels in macros

[russian]

if you are to execute a certain macro many times the labels inside of it must obviously be different or it MASM will give a label redifinition error. Is there a way, aside from @@/@b/@f, to make labels inside of macros that will not be duplicated if you run the macro many times??

You declare the labels as LOCAL. See Defining Local Symbols in Macros here:

As a demonstration, if you attempt to compile this:

Code Select Expand


    .486                       ; create 32 bit code
    .model flat, stdcall       ; 32 bit memory model
    option casemap :none       ; case sensitive

    locals MACRO
        LOCAL lbl
      lbl:
      .err <lbl>
    ENDM

    .data
    .code
start:

    locals
    locals
    locals
    locals

end start


You will get this output:
