Probably off topic, but it would be nice to see this in some future
version of PalmOS...
I worked in one GUI development environment which allowed you to specify
general regular expressions in the "constructor" when you created
a text field. The regular expression was used to do initial data
validation as the user entered text. For example, a text field
designed to enter a monetary amount (ie, $5.39) might have a regular
expression associated with it like "(\$)?[0-9]*\.[0-9]{2}" which
was used to do initial validation of the data. If the value in the field
didn't fit the regex, the field would have red highlight around it and
the OK button in the form would be greyed out.
It was nice to have, and saved us a lot of headaches and data validation
code.
