This *Command appends the VDU commands appearing on the screen to the specified file.
*SpoolOn [filename]
filename | Valid pathname specifying a file |
The spooling of data to a file is managed internally by OS_BPut. If OS_BPut generates an error, the spool file will be closed, and the error is then returned from OS_WriteC.
If no filename is given, the current spool file is closed.
The outputting of data continues until either a *Spool or *SpoolOn command (with or without a filename) is issued.
It is possible to temporarily disable the spool file without closing it by issuing OS_Byte 3.
