Hi,

In the middle of my IDL program, I need to check the type of a
variable in order to decide what to do with it. I mean, I have to
check whether variable1 is a STRING or FLOAT (for example). Like this:

IF variable1 "is STRING' do .....
else do ...

Of course "help, variable1" will not help as it shows the answer on
the consol and I can't use it that way. If anybody knows how to do so,
please let me know. Thanks.

Cheers
