'+N' & '-N' |
Control Drop/List Box Write Error |
Behaviour or GUI Display
Do Not Return Error 11: '+N'
Return Error 11: '-N'
Use '-N' to generate an Error 11 on a DROP_BOX WRITE " " or LIST_BOX WRITE " " if no such entry exists. '+N' tells the system to clear any selected item when writing a null string.
These mnemonics have no effect on multi-select List Boxes.
