Use this system macro to obtain attributes of pool types and pool
sections. This macro returns a pointer to an item in the record code
check reference table (IRCCR). Attributes of the item include the
following:
- Pool section name
- Pool section device type name
- Whether the pool section is active
- Whether the pool section is long-term or short-term
- Whether the pool section is duplicated records.
Format
- RCC=rccloc
- specifies the location of the 1-byte RCC.
- TYPE=poolloc
- specifies the location of the 3-byte pool type name.
- RETURN=(reg)
- specifies the register that will contain the address of the IRCCR item
whose address is to be returned. The address returned in this register
points to a data area structure according to DSECT IRCCR. The specified
register cannot be used as a base register for the TYPE or RCC
parameters.
Entry Requirements
This macro will not run when the caller is in 24-bit mode.
Return Conditions
- Control is returned to the next sequential instruction (NSI).
- If the requested pool section or pool type does not exist, the register
coded in parameter RETURN=(reg) will contain 0.
- The contents of register 14 (R14) and register 15 (R15) are unknown unless
specified as the return register
- On return, the register specified in the RETURN parameter will be mapped
to the IRCCR DSECT.
Programming Considerations
This macro can be run on any I-stream.
