An example from the online help: hFile = OPEN "/etc/hosts" FOR INPUT WHILE NOT Eof(hFile) LINE INPUT #hFile, sOneLine PRINT sOneLine WEND CLOSE #hFile You open the file, then input one line at a time. This is the classic way. Don't forget to close the file (see later). Another method is to load the entire file into a string, with: sString = file.load("/etc/hosts") then you must split this long string into a string[] using something like: sLines = Split(sString, "\n") At this point you have a string[] array you can traverse with "for each": for each sLine in sLines ... ... next Every single line, obtained by either the two methods, must be again splitted in tokes and loaded in the TreeView. About execute command then exit, I had no problems in doing this: shell "cd /usr/local/bin; xterm &" This launches the terminal emulator "xterm" in background. If you exit the application, the xterm stays there. It is true that open files, environment, signals and other thing may be inherited by the child process, but I think this can be solved by the ampersand in the end of the SHELL command. If you need more help, ask again.
