The assignfq command assigns a printer device driver to a spooler form queue. This printer driver is then used by the Output processor, or by FlashBASIC @() functions to generate special formatting commands such as boldface, cursor positioning, or underlining, when output is directed to the spooler.
assignfq form.queue{-n},device.name{,form.queue{-n} ,device.name{,...}}{(options}
| form.queue{-n} | Multiple form queues can be updated in the command, but each queue must have an associated device name. | |
| device.name | Name of the device to assign
to the specified form queue. If "null" is specified, unassigns a device
from the specified form queue. Warning: The device.name is limited to a maximum of 12 characters.

| options | c | Compiles the devices file item into the printer control block. |
Using a ? as a parameter produces abbreviated TCL help.
Printer drivers are located in the dm,devices, file. The current driver assignments may be displayed with the listabs command. A printer may have more than one form queue attached to it.
The printer control block is a binary item, (similar to a system-level dynamic array) that contains the codes and control strings pertinent to the device in question. Each system function ( @(-n) ) has its own array position, and the system cursor function searches this item for control strings such as clear-screen, clear to end of screen, and so on.
