Normalize cylinder number (TRKADDR NORMALIZE) z/OS DFSMSdfp Advanced Services SC23-6861-01 |
|
The format of the execute form of the TRKADDR NORMALIZE
macro is:
>>-+-------+--TRKADDR--NORMALIZE--+-,cchh--+--,REG=(rega)------>< '-label-' '-,(reg)-'
Reverses the 16-bit and 12-bit portions of the cylinder number and stores the result in the 32-bit register with the H digit so you can use a simple unsigned comparison. The CCCCcccH becomes cccCCCCH. Use this when comparing one cchh against another. Normalize each and do an unsigned comparison. |
