Thanks James & Mythili .....

You were both correct. Here's the format that finally worked.

/usr/OV/bin/addtrap -n ibm8272TsSys -l ibm8272TsTempThreshold \
   -i 1.3.6.1.4.1.2.6.66 -g 6 -s 1 \
   -o A  -c "LOGONLY" -t 0 \
   -S 1  \
   -D "This trap is generated when the system temperature
either exceeds 50 C or when it returns to normal(45 C)
after exceeding the temperature. The variable
ibm8272Ts2SysTemperature indicates the temperature
condition at the time of the event."  \
   -e ibm8272TsTempThreshold  \
   -F '$E $G $S $# args: $*'
