-------------------------------
I tried using the OCLplus editor, but keep getting an error.

I use a shortcut to point to the oclplus.exe & it has a command line of:
C:\MPS\ORION2\OCLPLUS.EXE -e orb21.txt
with the exe's all being in the C:\MPS\ORION2 directory.
If you can tell me what I'm doing wrong, I'd be very thankful.
By the way, the change I am hoping to make, is to alter plasma cannons so they are not auto-matically enveloping, like fusion beams for example.
