Webfacing, adding a hyperlink to the web settings of a dds file

Hello,

I'm trying to make a simple hyperlink in a dds file in my new Webfacing
project. This is the way WDSCi will make the Hyperlink

A*%%WB 12 FLD 4 fld=&{S0001CTL.OPTCODE}|value=&{MENUOPT.value}|func=ENTER

I want to be able to do something like this...

A*%%WB 12 FLD 4 fld=&{S0001CTL.OPTCODE}|value=&{MENUOPT.value.substr(0,3)
}+
A*%%WB +|func=ENTER

because the menuopt field in the display file has an edit word

A MENUOPT R O 6 2EDTWRD(' 0.')

and the "." is making the OPTCODE invalid in my application.

Does anyone have any suggestions???
