Syntax:  ! comment text

Discussion:
The exclamation mark (!) is the comment character.
It may appear anywhere in a report specification.
When the report is prepared, any text following the comment character is ignored.

History:
Starting with Release 01.02, the comment character may appear anywhere on the line.
Previously, the comment character was only recognized in the first position on the line.

Example:

 100   ! This report prints customer numbers and names
 200   !
 300   INPUT CUSTOMER     ! get data from customer file
 400   REPORT             ! prepare the report now
 500   ! 
 600   ! The following command prints the customer number
 700   ! and customer name
 800   !
 900   PRINT CUST.NUMBER;CUST.NAME
1000   END
