DO VALUES and DO INDICES with Arrays

With do values the counter takes the value of each array element in turn:

!Pump[1] = ’Fred’

!Pump[20] = ’Tom’

!Pump[10] = ’Jim’

do !Name values !Pump

Sp array element is $!Name

This will produce the following output:

Array Element is Fred

Array Element is Jim

Array Element is Tom

On exit from a do values loop PML destroys the loop counter variable.

With do indices the counter takes the value of each array subscript at which an array element is stored:

!Pump[1] = ’Fred’

!Pump[20] = ’Tom’

!Pump[10] = ’Jim’

do !IN indices !Pump

!Value = !Pump[!IN]

SP Array Element $!N is $!Value

This will produce the following output:

Array Element 1 is Fred

Array Element 10 is Jim

Array Element 20 is Tom
