MAXBLK: Maximum block size option z/OS MVS Program Management: User's Guide and Reference SA23-1393-00 |
|
You can specify the maximum size of a text block within a load
module by coding the MAXBLK option in the PARM field as follows:
MAXBLK=n The MAXBLK value n specifies the length of the text block in bytes and must be an integer between 256 and 32760. This option allows you to ensure that a load module can be copied to a device with a smaller track size without reblocking. If you specify value2 on the SIZE option but do not specify a MAXBLK value, MAXBLK will default to one-half of value2. If you do not specify either value, MAXBLK defaults to the block size of the data set. If you code the DC option, MAXBLK and SIZE are both overridden and MAXBLK is set to 1024 bytes. We recommend that you allow the system to determine the block size for program libraries. However, if you need to control the block size, we recommend that you use the MAXBLK option instead of the SIZE option. This option is only valid when binding load modules.
