Support for NK4 disks

In BS2000 there are two formats of PLAM libraries supported by LMS:

• the 2K-oriented format (NK2 PLAM file)

• the 4K-oriented format (NK4 PLAM file)

The COPY-LIBRARY statement converts from one format to the other (cf. example under COPY-LIBRARY, "COPY-LIBRARY"). The user determines the appropriate format in the BS2000 command ADD-FILE-LINK and the BUFFER-LENGTH= operand:

NK2 PLAM file:	BUFFER-LENGTH=STD(SIZE=1)
NK4 PLAM file:	BUFFER-LENGTH=STD(SIZE=2)

LMS supports both library formats. It also supports NK4 disks with the ADD-ELEMENT and EXTRACT-ELEMENT statements.
