How about:
s=' '
readf,unit,s
array = strsplit(s,',',/extr)
maybe?

How about creating a template and then using the template along with
READ_ASCII?
IDL> template = ASCII_Template()
IDL> Read_ASCII(filename, TEMPLATE=template)
If you need to reuse the template, just Save it off somewhere and
Restore it in your program. I have a directory full of IDL Save files
each of which is a single template for the specific file types I work with.
