Dear all

just again a question on this

I have recognized that it is easier to do nothing

plot,['1.2','1.3','1.4'],['1.2','1.3','1.4']

I wonder a little bit about this but it seems to go right. By this the
routine who is called will set the type.

IDL> a='1.23'
IDL> print,a+0.1
1.33000

IDL> b='99.99'
IDL> print,b gt 100
0

What else should be checked?

cheers

Reimar
