The hide command temporarily stores the contents of the field at the current line in a system-controlled memory called the HIDE AREA.At an interactive event,the contents of the field is restored from the HIDE AREA. When calling a secondary list from a list line for which the HIDE fields are stored, the system fills the stored values back into the variables in the program. In the program code, insert the HIDE statement directly after the WRITE statement for the current line.
