MCH0601 on CVTCH

["sunil K Tripathi" <suniltripathi@xxxxxxxxx>]

Hi all,

I am trying to extract the packed value from a string what i did is this :

 $HtoC           PR     extproc('cvthc')
  P$TgtChar               *
  P$SrcHex                *
   P$TgtBytes           10i 0 value

 $CtoH           PR          extproc('cvtch')
   P$TgtHex            64a   options(*varsize)
   P$SrcChar           128a   const options(*varsize)
   P$SrcBytes          10i 0 value

callp     $CtoH(w$hex:%subst(w$FldValue:1:a$Length(i)):
                          a$length(i))

here w$FldValue is a 10k character containing the packed data, length of packed 
data is a$length(i)


At this callp statement i am getting MCH0601
my joblog says:

Space offset X'2AFFEFF0' or teraspace offset X'0000000000000000' is  outside 
current limit for object QPADEV000CSGSKT022  146163.
The call to cvtch ended in error (C G D F).

MCH0601 received by procedure DBC. (C D I R)

I an wondering what's the problem here?

Is there any other alternative to extract the packed value from a character 
string???

will appreciate any help
thanks
sunil.
