'sys' <shell-command parameters>This keyword is used to issue any shell command (unix or dos shell). For example to move files created by the 'send' command to certain file names or/and locations and to start the analysis. On certain platforms cgx will not wait for the completition of the command if the '&' key was provided as the last argument of the command. Otherwhise cgx waits until the command was completed.
Therefore before you open a foreign command file (usually with the ending .fbd or .fbl) scan for "sys" and evaluate the command line.
To activate the “sys” command permanently add
'allow_sys'in your configuration file ('.cgx' in your home directory).
