IS_LOADED

  .  Summary

  is_loaded(str <filename>);

  .  Description

  The is_loaded function is used to determine if a SALT script, in-
  dicated by <filename> is currently loaded into memory. The script
  can be in memory if it was explicitly loaded with the load_script
  function, or is still in memory because it previously was run and
  did not finish executing. If filename does not include an extension,
  ".SLC" is automatically added.

  .  Return Value

  A non-zero (TRUE) values is returned if the indicated script file is
  in memory, otherwise a zero (FALSE) value is returned.

  .  Example

  if (!is_loaded("TESTSCR"))   // make sure script is in memory
   load_scr("TESTSCR");
