As far as I know, tape space is considered "never-ending"......If you run out of space on a volume, the system just keeps writing on another.....

Hi,

If you would like to know rather the space used by some tape file, then below JCL can work for you:

Code:
//STEP010  EXEC PGM=SYNCTOOL         
//TOOLMSG  DD  SYSOUT=*             
//DFSMSG   DD  SYSOUT=*             
//DD01     DD  DSN=TAPE_FILE_NAME,   
//             DISP=SHR             
//TOOLIN   DD  *                     
   COUNT FROM(DD01)                 
/*                                   
//*                                 


Check the TOOLMSG & DFSMSG after completion of the JOB. One of them'll give you the LRECL & BLOCKSIZE of tape file. Perhaps that info can be of your use.
