Allocating optional image ISPF library

The data set described in Table 1 is not a required ISPF library. You must allocate it only if an application in GUI mode uses images.

Table 1. Image Data Set
DDNAME	Description	RECFM	LRECL	BLKSIZE
ISPILIB	Image Input Library	FB	80	(See note)

Note: The block size must be a multiple of 80. You can specify BLKSIZE=0 to use a system determined block size.

If you plan to use ISPF's image support, you must allocate the image input data set to ddname ISPILIB before using the images. You can accomplish this by allocating the image input data set before you invoke ISPF. Image files in Graphics Interchange Format (GIF) should reside in this input data set. This data set must be a partitioned data set. It can be allocated with DISP=SHR.

Note: The LIBDEF service does not result in the allocation of ISPILIB.

ISPF ships sample image files in the SISPSAMP library. The ISPF panel ISR@PRIM uses the sample image files ISPFGIFL, ISPFGIFS, and ISPEXIT. You can copy the sample image files to your own image input data set allocated to ddname ISPILIB.
