ASSIGN [logical name:] [directory] * ASSIGN will assign a logical device name (must end in a colon (:) ) to a disk directory. eg. assign z: df1:zshell_source Now if you do a DIR Z: you will get a directory of df1:zshell_source. Similarly, the default device names can be reassigned. eg. assign libs: df1:libs * Typing ASSIGN with no parameters, will list the current device assignments. eg. assign ASSIGN is compatible with the AmigaDOS Assign command.
