Re: Data validation, mapping, and error handling

I've been working for the past couple weeks on a streamlined interface 
for handling HTML form validation, mapping, & error handling, and hoped 
to give a final status before the end of this month.

This new interface automatically validates and maps HTML form elements 
to externally described data structures, and visa versa.  I've provided 
links to RPG and DDS sample source.

The wtnRecGet() procedure retrieves HTML form elements, validates them, 
and maps them to sub-fields in a data structure.  In return, the 
wtnRecWrt() procedure writes data structure sub-field values to HTML 
forms.  Data validation, mapping, and output formatting is implemented 
via DDS specifications.

This significantly streamlines the interface for handling HTML forms in 
RPG applications.  It's quite comparable to 5250.
