I created this form custom method to allow me to only update the field

if the value has changed.  This replaces lots of unconditional REPLACEs

in a form.

LPARAMETERS tcTable, tcField, tvValue

LOCAL lvCurrent as Variant

lvCurrent = EVALUATE(tcTable + "." + tcField)

IF lvCurrent <> tvValue THEN

    REPLACE (tcField) WITH (tvValue) IN (tcTable)

ENDIF

(This is in theory yet...implementing it soon.)

So instead of

    REPLACE order.cost4des WITH 'Fuel Surcharge'

I call

    thisform.UpdateTableValue('order','cost4des','Fuel Surcharge')
