[...]would be good if there was a way around this, anyone know?
or will i just have to change IFS back to OLDIFS at the start and end of every function?[...]
Well, it depends. The following syntax affects the IFS only for the read command inside the while loop, so you don't need to worry/restore the previous value of IFS for the statements after the loop.
Sometimes it's convenient to force a sub-shell execution to avoid affecting the current shell environment, but it depends on what exactly you' re trying to achieve.

I am using bash and resetting IFS as below when reading the command line arguments. I do this so I can call my script as in Ex1.
Ex1: ./synt2d-ray3dmod.bash --xsrc=12/20/30
This allows me to split both sides so that when I do "shift"
I can get 12/20/30
