F.GSCN - get a copy of the SCN table.

Usage:

f.gscn();

Description:

F.GSCN GETVEC's a block of memory and copies the System Configuration Name table into it. The table size (which is the getvec size) is one greater than the maximum index into this table.

The pointer to this table, with the GETVEC size in the upper half, is inserted in the external "f.scntab".

This function also sets the external "f.scn". Under GCOS3, F.SCN is set to the value of .CRSCN. Under GCOS8, F.SCN is set to the first word of segment SD.SCN.

Notes:

Although F.GSCN works in the current release of the package, users should generally use the mapping functions SN.SCT or F.DEVN instead. If walking all devices on the system is needed, IO.QRY should be used. F.GSCN may be discontinued in some future release.
