I have come across PDSFAST and cant really find any documentation explaining the supported sysin cards on the internet.

Code:
//VERIFY   EXEC PGM=PDSFAST,                                           
//            REGION=4096K                                             
//SYSPRINT DD SYSOUT=*
//PDS      DD DSN=&NAME, DISP=SHR                                           
//SYSUT3   DD UNIT=SYSDA,  SPACE=(CYL,(5,5))                                             
//SYSUT4   DD UNIT=SYSDA,  SPACE=(CYL,(5,5))                                               
//SYSIN    DD *
 VERIFY INDD=PDS,LIST=NO     
/*


I have to migrate this onto Linux. So i was wondering what the VERIFY really does.
I found a link that says
Its checking for I/O errors. What does this really mean for a PDS ?

Thanks !
