How to check if a tool, partition, and variable are registered before envSetVal?

drdanmc

Is there a way to protect calls in a .cdsinit to envSetVal with something that makes sure the tool, partition, and variable are available to be set?  For example, if you launch the QRC gui (qrcui from command line) it will load your .cdsinit but doesn't like envSetVal calls for "layoutXL" (for example).  I can protect functions with things like:

when( isCallable('calRegisterSpecialFunction)

  calRegisterSpecialFunction(....)

)

The envSetVal calls just cause warnings which can be ignored but it makes me feel better to not have lots of warnings all the time.

Thanks

-Dan
