First - you can't use your user name as the member name.
Why not ?
The 100 in the SPACE param will allocate 100 directory blocks to the PDS. Enough for approx 600 members.
Something to remember about allocating directory blocks. Each track will hold 45 directory blocks, except for the last track in the directory which will only hold 44. I usually switch this around and say the first track has 44 blocks and all others have 45.
So, for space efficiency, I would have used either 89 for two tracks of directory, or 134 for three tracks of directory.
The number of members each block holds depends on whether you have ISPF statistics on or off. With ISPF stats on, there will be 6 members per block, but more with ISPF stats off. I usually use 6 as a guidline whether ISPF stats are on or off in my PDS.
