One way to get file data in Tcl is to 'slurp' up the file into a text variable. This works really well if the files are known to be small.

# Slurp up the data file
set fp [open "somefile" r]
set file_data [read $fp]
close $fp

Now you can split file_data into lines, and process it to your heart's content. NOTE: The mention of split is important here- input data is seldom well-behaved/structured, and needs to be processed in this way to ensure that any potential Tcl metacharacters are appropriately quoted into list format.

# Process data file
set data [split $file_data "\n"]
foreach line $data {
# do some line processing here
}
