Re: Display File Issue within RPGLE

First off, what's the big deal in validating something a second time.  You
are talking maybe milliseconds of processing time to repeat a validation.

But if this is what is required.  Create save fields to hold the previous
value of the screen fields.  Then only when they change do you do your
validation.  You can use a separate indicator for each field to position to
a field on the screen.

I have a display file which contains about 7 fields which the user
needs to complete.  We need to use CHECK(ER) in order to validate the
input as the user is entering it.  All of this is simple enough,
however I need to not only check these fields but also know when the
user has entered the last field.

In addition I am hoping to find a simple way to move the cursor from
each field to the next corresponding field for each iter.

I know that I could set the DSPATR(PR) with an indicator on each field
once it has been validated and that will move the cursor along as
well, but that also prevents the user from going back and editing
information that although may be valid, is not correct.

This would also help avoid looping through unneeded sub-routines each
iter as well as fields that have been already validated do not need to
be validated a second time, etc.

Suggestions on how some of you would do it?

Mark.
