BTS0126W UNABLE TO FIND LTERM: `lterm` IN DFSCLV0`x`

Explanation
 The first LTERM name in TRXIN
records does not
exist in DFSCLV0x, when the transaction BTSAISR0
runs with ./E IMSSUF=.  x is the suffix code specified
by ./E IMSSUF=.

System action
 IMS Batch Terminal Simulator ignores ./E
IMSSUF=. and runs with a default device type
(DEV TYPE=(3270,2),FEAT=IGNORE). 

User response
 Correct the value of ./E IMSSUF= in BTSIN or
SKIP= in CNTLCRDS, and rerun the job.
