Hi,
(I am not sure if this message will make it through, lets hope that it does)

I am trying to check the existence Houdini specific variables (Not ENVIRONMENT variables).

I am using, for example:

echo `isvariable(“VER”), this returns 1

but then:

echo `ishvariable(“MAPU”), this returns 0
echo `ishvariable(“PT”), this returns 0

$MAPU and $PT are Houdini variables, why the check returns 0 (FALSE)?

Any ideas?
Thanks.
