Re: MCH0601 & Teraspace

I do not know what the problem is but it is hardly related to teraspace.
MCH0601 is a generic message, space offset in a message is non-zero - so
this message applies to simple space.
Space class x'04' is  "04-implicit process space for activation group-based
heap storage" - from the same message.
Check for use of heap-allocated storage and check how you use pointers -
you can overstep to unallocated storage.

I have an RPG program that uses API's QsnCrtInpBuf, QsnReadScr and
QsnRtvDta Dynamic Screen Manager API's.    Under V4R4M0 they worked
fine.  We have gone to V4R5M0 and now get the following message:

I get this after the 3rd API is called (there are no errors returned
from the API themselves).  The line of code is:

C                   Eval      BufferDta = BufferDtaFld

Fields defined:

 D BufferPtr       S               *
 D BufferDtaFld    S          32767    Based( BufferPtr )
 D BufferDta       S          32767

I have gotten the lastest cum PTF and got all PTFs related to teraspace
applied.  Still the same message.  The first time this is run it is
okay, but the second time they get the message.

Any help would be appreciated.
