LOCALS           Enable local symbols                               Directive

  LOCALS [prefix]

    Enables block-scoped symbols, and optionally sets the two-character
    local symbol prefix.

    Local symbols are automatically enabled in Ideal mode.

    Example:    locals __
                ;...
                        test    ax,1
                        jnz     __odd
                        dec     ax
                __odd:

    Example:    Ideal                   ; Default local symbol prefix @@
                lab1:                   ; Start of scope
