[Newbies] pathnames

[Chris Kassopulo]

Hello Ron,

Thanks for the direction.

To get the list of filenames in a directory, I do:

"return the list of file names from a directory"
aDirectory := FileDirectory on: '/home/cpulo/data'. 
aDirectory fileNames.

or

aDirectory := (FileDirectory on: '/home/cpulo/data') fileNames.

Without the parens the path is taken as a ByteString.

It Squeaks!

Chris
