a statement to multiply two or more numeric values
Format
Remarks
multiplies each of the second arguments by the first argument and overwrites the old value of each second argument, unless the third argument specifies a different storage place
so, for example, MULTIPLY 2 BY X Y Z will double the values of X, Y and Z
all three arguments obey the rules of sufficient qualification
the first argument can be a literal
if the second argument is a literal, the third argument is mandatory
any of the three arguments can be an identifier defined with a numeric picture clause (free from A and X)
