Slide 27 of 68
Notes:
Heres an example of a loop for retrieving all the elements of a string. In the example, elements of the string are delimited by commas.
Note that the index is incremented before the element returned is examined. This is one way to help avoid locked loops. Ignoring null elements might not always be desirable.
When F$ELEMENT returns a comma, control is transferred to the EXIT_LOOP_1 label.
