21. The LOCAL directive

• The LOCAL directive must be on the line immediately following the PROC statement with the following syntax:

      LOCAL vardef,
            vardef,
            vardef...
  

• Each vardef defines a local variable.

• Local variable definition formats:

      LOCAL label:qualifiedtype,
            label[ count ]:qualifiedtype
  

  where

  • label is the name of the local variable.

  • count is the number of array elements, making local variable a simple array on the stack with count.

  • qualifiedtype is a valid MASM data type.

• For example,

          ARRAY_SIZE     EQU     20
      myproc PROC NEAR32 C USES edi, arg:DWORD
          LOCAL myarray[ ARRAY_SIZE ] : BYTE
          LOCAL var2 : WORD
          .
          ret
      myproc ENDP
