Annoying SQLPLUS Problem

How can I stop an explain plan from autotrace from wrapping? It doesn't on some platforms, but on my NT machine, it does:

Execution Plan

   0 SELECT STATEMENT Optimizer=CHOOSE (Cost=10 Card=1 Bytes=36)    1 0 PARTITION RANGE (ALL)
   2 1 TABLE ACCESS (BY LOCAL INDEX ROWID) OF 'M' (Cost=10 Card=1 Bytes=36)

   3 2 INDEX (RANGE SCAN) OF 'MOC_ANSWER_TIME_I' (NON-UNIQUE) (Cost=9
Card=1) Received on Sun Dec 01 2002 - 05:59:25 CST
