SPL

Syntax: SPL {input | #ch} [TO {output | #ch}]
Location: Toolkit II, THOR XVI

The command SPL sets up a small Job which runs at a low priority and acts as a print spooler, reading the whole of the input data from the given input device as quickly as possible and then just outputting the data when it can. 

SPL is mainly for outputting files to a printer in the background.

If however, a file is specified as the output, the SPL command acts like COPY_O, except in the background.

If output is not specified, the SPL command uses the default destination device.

Existing channel numbers may also be specified as the input and output names, provided that both channels are already open for input and output respectively.

Example:
SPL flp1_Example_txt TO SER
SPL_USE SER:SPL flp1_Example_txt

CROSS-REFERENCE:
See COPY_O and SPLF.
SPL_USE and DEST_USE allow you to alter the default destination device.
