Check for existance of objects from within a program

Create it as a module and stick it in  a service program. One thing you should note, if you are not authorizied to the object, i still flag the
object as existing. CHKOBJ doesnt work this way, but this way seems to work better for what i usualy use the procedure for.

If you're not on RPGIV, i think i can find an RPGiii version around somewhere.
