Interesting results.  I had to mess with it a bit:

d pBaseDS         ds
d pBase                           *
d pDataDS         ds
d pData                           *

c                   eval      pBase = *null
c                   eval      pData = pBase + 32
c                   eval      *inlr = '1'
c                   return

I got the following results:

eval pBase       PBASE = SPP:*NULL
eval pData       PDATA = SPP:*NULL
eval pBaseDS:x   00000    00000000 00000000 00000000 00000000
eval pDataDS:x   00000    AF000000 00000000 00000000 00000020

I don't have a clue what this means.  Just thought I'd share it.
