USAGELOG

  .  Summary

  usagelog(str <filename>);

  .  Description

  The usagelog function is used to manipulate the Telix usage log fa-
  cility.

  If <filename> is an empty string (""), Telix will ask for the file-
  name to open the usage log to, as if the user had pressed Alt-U in
  terminal mode.

  If <filename> contains a valid filename, the usage log is opened to
  that file. The standard usage log is usually called "TELIX.USE".

  If <filename> is "*CLOSE*", and the usage log is currently open, it
  is closed.

  .  Return Value

  A value of -1 is returned if there is a problem performing the indi-
  cated operation, otherwise a non-zero (TRUE) value is returned.

  .  Example

  usagelog("TELIX.USE");
