= Multiple Specification (5 of 9) =
It is possible to make multiple simultaneous assignments by enclosing a list of variable names in parentheses on the left of an assignment arrow.
{{{
             (A B C)← 1 2 3
             A
       1
             B
       2
             C
       3
}}}
A scalar to the right of the assignment arrow will be assigned to every item on the left. This is known as '''scalar extension'''.
{{{
             (A B C)←5
             A
       5
             B
       5
             C
       5
             (A B C)← 'HI' 'THERE' 'FOLKS'
             ⍴A                      (A assigned 'HI' and so on)
       2
             (A B C)←⊂'HI' 'THERE' 'FOLKS'
             ⍴A                      (A, B and C assigned the enclosed vector
       3                              to the right of the assignment arrow)
}}}

<!> Caution: Do not omit the parentheses if you are trying to do multiple specification, as in:
{{{
             A B C←5
}}}
This expression will assign the value {{{5}}} to {{{C}}} and then attempt to evaluate the resultant expression. See also the discussion of binding strengths.
