Setting the Display Mode of a Table Field
You can set a table field's display mode at run time using the mode constant. The syntax for this is:
set_frs field formname (mode(fieldname) = value)
You can use either character string literals or program variables to represent the fieldname, formname, and value. The value must evaluate to one of the following: fill, update, read, or query.
If you change the table field's display mode to or from query, the data set is cleared. For a complete description of the effects on the table field when you change from one mode to another, see Table Fields.
