Allocating and Initializing a VLS Library

A VLS file is organized logically as a collection of members. A member name identifies a member. The following table shows the required name length (NAMELEN) for each CA Ideal VLS file. The block size can be any size convenient to the device type, except that each file type has a minimum block size. The data is actually stored in VLS internal format in fixed length blocks. Default (installed) and minimum block sizes are shown in the following table. Data compression and space recovery are automatic.

OS	File	Required Namelen	Installed Blksize	Minimum Blksize
	IDAT	24	1960	960
	IDDVW	40	4000	4000
z/OS	ICxxxSRC	24	1960	960
	IDxxxPNL	24	4000	4000
	IDxxxOBJ	24	4000	4000
VSE	IDLxxxS	24	1960	960
	IDLxxxO	24	4000	4000
	IDLxxxP	24	4000	4000

The following files that CA Ideal uses are installed with CA IPC:

File	Required Namelen	Installed Blksize	Minimum Blksize
ADRLIB	24	4000	4000
ADROUT	11	4000	4000
ADRPNL	24	4000	4000
