LOCAL (MASM)
In the first directive, within a macro, LOCAL defines labels that are unique to each instance of the macro.
LOCAL localname [[, localname]]...
LOCAL label [[ [count ] ]] [[:type]] [[, label [[ [count] ]] [[type]]]]...
Remarks
In the second directive, within a procedure definition (PROC), LOCAL creates stack-based variables that exist for the duration of the procedure. The label may be a simple variable or an array containing count elements.
