 //STEP10   EXEC PGM=IDCAMS                 
 //OUTFL    DD DSN=P76B.VSAM1.KSDS,DISP=SHR 
 //SYSPRINT DD  SYSOUT=*                     
 //SYSOUT   DD SYSOUT=*                     
 //SYSIN    DD  *

HI-A-RBA---------1013760 - Highest allocated RBA
HI-U-RBA----------506880 - Highest used RBA

So you have 506880 bytes left to use

Hi,

HI-A-RBA is Highly allocated relative byte address - Maximum space allocated for VSAM dataset.

HI-U_RBS is Highly used relative byte address - Actual space occupied right now by VSAM dataset.
