  Hi Anna

  I did not understood very well your question, but how about:

  set infile [open textfile r]

  while {[gets $infile line] >=0}
     # reads 4th column
     set value [lindex $line 3]
     # do something with $value
     puts $value
  }

    Subject: vmd-l: tcl-reading files

    Hello,

    I'm writing a tcl script in which I need to read numerical values of variable length from a file.
    Is there any simple way to read from files string after string and not sign after sign?

    To make the question more clear, the lines are:
    "text1 text2: -1.2345 23.5 -234.56731"
    "text154 text2: 5.23 -2.987 -2.531"
    and I would like to read the fourth string from each line (in this case: 23.5 and -2.987).

    Best Regards
    Anna
