	And how do you know that you have *permission* to cd into the directory?
	Knowing that it is a directory isn't enough.
	
	


---
To know if you have access use the expression flags in the CSH manual
pages.

For example to know if you have read access and the directory exist do:

if (-d directoryname) then
        if (-r directoryname) then 
                ls directoryname
        else
        echo no read access
else 
echo directory does not exist
endif


I hope this helps.
