You might, for example, write an entry/exit procedure that totals the weights of ordered items and calculates the appropriate shipping charge upon entry in a field. When you want the procedure to check a value that has been entered in a field, the value must be loaded into a variable, not a column. To load the value into a column, use an expression in the form to set the column equal to the variable.
The R:BASE SKIP command is designed for use with entry/exit procedures in forms. Use SKIP to tell R:BASE to skip over or skip back a specified number of fields, or skip to a specified field.
For example, the following entry/exit procedure tells the form to skip to the field with the column amount if there was any value in the variable vcashtype.
IF vcashtype IS NOT NULL THEN
SKIP TO amount
ENDIF
RETURN
