control variable in online screens

Answer Posted / jamil ahmad

In a layman terms, a control variable (#CV (C) does only
two but very useful functions.

1. Do you want the user to overlay the field with new value
or you want to protect the field, for example, if an Order#
is a system generated number, you would want that to be
modified

2. If the fields not protected, was it a modified?
For example, if the SSN was modified then validate it
otherwise take no actions against the field. Juts my 2 cents

Is This Answer Correct ?    2 Yes 0 No
