DASD and other storage required

HLASM Installation and Customization Guide
SC26-3494-05

The DASD storage requirements of High Level Assembler must be added to the storage required by other programs having data in the same library. An estimate of required space is the data set's current allocation plus the storage required by High Level Assembler.

Auxiliary storage is needed for the system history file, for the library and for an intermediate work file (IJSYS03) on a direct-access storage device.

At a minimum, the library must have free the number of library blocks shown in Table 1. A library block equals 1 kilobyte. Therefore, 10 library blocks equal 10,240 bytes.

Table 1 also allows for space for service application.
