xterm question (translating Solaris Korn scripts to run on RHEL)

I'm translating some Korn scripts used on Solaris to run on RHEL 6.4. The scripts use:

dtterm -sl 25000 -geometry 133x18+0+0 -display ${GLOBAL_HOST_NAME}:0.0 -e $0 -s ${DTNG_SIM_PROTOCOL} -f ${DTNG_FOM_NAME} -r ${DTNG_TESTCASE} -X ${DTNG_GATE_EXEC} &

I assume I'll need xterm? Can I use xterm to start a terminal and begin running some executable in it?
