IDL> print,!version

With the name argument of getenv set to capital letters I get the right
answer, but in small letters 'pwd' returns the null string. However, if
I use the same command on the UNIX platform I get

image1 [1] pwd
/disks/sprite/disk1/hfrey/idl/image/wic
image1 [2] PWD
PWD: Command not found

and UNIX does not like the capital letter 'PWD'.

Any explanation?
