Allows you to add explanatory text to code. The comment begins with /* and ends with */. This type of comment can wrap over multiple lines.
The r-comm.p example uses comments to document the history of procedure modifications.
r-comm.p
/* Procedure written 9/5/87 by CHC revised 9/27/87 by DG */ FOR EACH Customer NO-LOCK: DISPLAY Customer.CustNum Customer.Name Customer.Contact Customer.Phone. END. |
The r-comm2.p example uses comments to describe what the procedure does.
r-comm2.p
/* Step through unshipped orders */ FOR EACH Order NO-LOCK WHERE Order.ShipDate = ?: /* Display order date, promise date, terms */ DISPLAY Order.OrderDate Order.PromiseDate Order.Terms. /* FOR EACH OrderLine OF Order NO-LOCK: /* Display all OrderLines of each Order */ DISPLAY OrderLine. END. */ END. |
The comment symbols that enclose the inner FOR EACH block turn that block into a comment for testing purposes. You can nest comments, so ABL correctly processes any comments already in the bypassed code. Both multi-line comments and single-line comments can be nested inside a multi-line comment.
