Hi Parin, the data set has 5 records in each block of 7.630 bytes. A track of 56.664 bytes (assuming 3390 DASD) can contain 7 of your blocks. That are 53.410 bytes per track. The data set has allocated 297.141 tracks, each 53.410 bytes of data. That are 15.870.300.810 bytes (which fit in an amount of 15.498.341 Ki-bytes, 15.136 Mi-bytes, 15 Gi-bytes) of a maximum size. Well, may be the last track contains only one record of 7.630 bytes or full 7 blocks with 35 records (267.050 bytes). When you transfer the data from MVS to e.g. Windows you might need to consider certain other effects, e.g. insertion of new-line symbols, efficient handling of blank symbols (remember, you have RECFM=FB and potentially a lot of X'40') or character set conversion (especially when translating between single byte and double byte codes). So as usual: "results may vary" and "clearly it depends".

I cannot download the file and check the same as I know the file size would be over 50 GB and I don't want to fill up my hard disk. The dataset has following details - Device type . . . . :,3390 Record format . . . :,FB Record length . . . :,1526 Block size . . . . :,7630 1st extent tracks . :,15000 Secondary tracks . :,1500 Current Allocation, ,Allocated tracks . :,297,141 ,Allocated extents . :,190 , , , , Current Utilization, ,Used tracks . . . . :,297,141 ,Used extents . . . :,190 I tried searching this on Google, but didn't get anything. I know that there is some formula for this. Any help will be much appreciated.
