  _scr_chk_key

  .  Summary

  int _scr_chk_key;

  .  Description

  Between every command while executing a script file, Telix checks
  the keyboard buffer to see if the user has requested an abort. This
  however gets in the way of the inkey function among others. As well,
  it is sometimes necessary to stop the user from being able to abort
  the script. If _scr_chk_key is set to zero (FALSE), Telix will no
  longer check for user aborts requests during script execution. Set-
  ting it back to non-zero (TRUE) will turn the checks back on. When
  modifying this variable in a script file, it is a good idea to save
  the old state in a scratch variable and restore it when done.
