Description
The VARREAD() function is synonymous with the READVAR() function. The VARREAD() function returns the name of the current @...GET variable being processed by a READ command. The VARREAD() function is most useful if used in conjunction with the @...GET...VALIDATE command and a validation procedure used to validate more than one field/variable.
Example
// Pop-up choice list called from a field validation procedure choices parameters m_input //if the [HELP] key is pressed if m_input = "HELP" m_exp = iif(varread()="acc_no","account", "supplier") select codes save screen set message to "Select code. ^C to abandon." menu browse &m_exp at 5,30 to 15,40 quit clear restore screen // if a selection was made if not empty(menuitem(),3) set fieldval to left(menuitem(),3) set validate on endif select accounts else // validate as required endif return
