Is there a way to have the contents of a field on a card change when a
global variable (in this case an array variable) is changed?
I have a multiple card application that I'm converting from Tcl. One of
the things I like about Tcl is that a field has a parameter called
-textvariable) that points to a location that holds the contents to be
displayed in that field. If you change the contents of the field, what
you are really changing is the global variable and vis-versa. This
allows me to put a field on several cards (in different locations on
each card) and when I read a new record, I just put the results into a
global array. I'd like to try and do the same thing in Rev if it's
possible.
I'd like to avoid writing a script in the "readrecord" function that has
to know the names of every field on every card that needs to show that
information, and then looping through and setting the text of each of
those fields to the contents of the global variable. This seems like it
would be very hard to maintain system.
Thanks,
Len Morgan
