DV.TYP - get device type information.

Usage:

type = dv.typ(dev, bcdflag);

Where:

dev: identifies the device being queried. This is either the 3-character BCD device name, or the negative of the SCT value.
bcdflag: indicates what type of information you want. If "bcdflag" is zero, the result is the 18-bit device type number. If "bcdflag" is 1, the result is the device type name (six BCD characters).
type: is either a type number or type name, as dictated by "bcdflag".

Description:

DV.TYP looks up device type information. Before SR4500, you obtained this information by accessing the 6-bit device code in .LSCT1 or .CRCT1. However with SR4500, the device code expanded to 18 bits, and a table was added to GCOS8 itself with the corresponding BCD names. When possible, you should use DV.TYP instead of the B library external table DV.NAM.
