SUM: Sum of an Array or String Argument

Sum of all elements in an entire array, or sum of the ASCII values of all characters in a string. More versatile is the inline-loop construct.

• return the sum of all the elements in an entire array
  • result = SUM( array )

  e.g.	REAL :: array(3, 4)
  array = 3^ $	3 9 27 81 243 729 2187 6561 19683 59049 177147 531441
  sum = SUM( array )	797160
  sum = +( array ) ! alternative is InlineLoop	797160

• return the sum of the ASCII values of all characters in a string
  • result = SUM( string )

  e.g.	result
  sum = SUM("Hello World")	1052
  sum = +( ICHAR("Hello World") ) ! alternative is InlineLoop	1052
