Ctrl Command auto_change
Function activates an automatic list change
Integration Pascal:
procedure auto_change;
C:
void auto_change(void);
Basic:
sub auto_change()
Comments • The auto_change command should only be used when working with two lists (up to
4000 commands each). This command should only be used if a list is currently
executing, or if it has already executed. Additionally, the other list should have already
been loaded and closed.
• With automatic list changing activated, the next list will start automatically after the
current list is finished.
• For each subsequent list, use a separate auto_change call.
• The current status of both lists can be read with the commands
get_status (page 86) or read_status (page 100) .
• See "Automatic List Handling", page 13 .
