A few months ago I assisted a customer who was having difficulty installing SimpList. The installation instructions specify the sequential data set the XMIT files are uploaded to MUST be allocated as BLKSIZE=3120, but the installer specified BLKSIZE=0. I don't remember exactly what problem this caused, but I do know that once the BLKSIZE was changed to 3120 the installation went smoothly.
