Applications are called "modes" on Pocketviewer. With the procedures you can get the names of the modes ( MODENAME), find a mode by name ( MODEFIND), start the mode ( MODEJUMP), get its version ( MODEVER$), information about the mode ( MODEINFO) or get the according icons ( MODEICON).

Mode numbers besides 8 are assigned to builtin applications. All addins have mode number 32 (obsolete: 8) and a submode number between 0 and 255 (obsolete: 15).
OWBasic 5.2 and later supports Add-Ins packed by AddInPacker.
