Return to Statement

Block IF Example 3

The following example contains a BLOCKIF construct using several ELSEIF statements with the ELSE statement.

   IFTHEN/a>b
   d=b
   f=a-b $$ End of first block
   ELSEIF/a>c
   d=c
   f=a-c $$ End of the second block
   ELSEIF/a>z
   d=z
   f=a-z $$End of third block
   ELSE
   d=0
   f=a $$ End of fourth block
   ENDIF

There are four statement blocks in this example (one for each BLOCKIF statement except ENDIF). If a is greater than b, the first block is executed. If a is not greater than b but is greater than c, the second block is executed. If a is not greater than b or c but is greater than z, the third block is executed. If a is not greater than b, c, or z, the fourth block is executed.
