Hello, I am a complete beginner in IDL so please bear with me. I am trying to plot an ASCII file. I do the following: First I find the path of my file using: C:\Program Files\ITT\IDL71\desktop\overnight.lvm 'overnight.lvm' is the ASCII file. I then create a plotting template: plotTemplate = ASCII_TEMPLATE( ) and then: plotAscii = READ_ASCII(FILEPATH('overnight.lvm', SUBDIRECTORY= $ ['desktop']), TEMPLATE=plotTemplate) My question is. How do I point to the file using the filepath I know from above. What is the syntax I have to use. I have tried all sorts of combinations but with no luck. The above gives an error. Thanks, Daniel     IDL> path=FILEPATH('overnight.lvm',SUBDIR=['desktop']) IDL> print, path
