Location HOTKEY II

The first variant of this function is very similar to HOT_CHP except that it will only start up a new copy of the program when the specified hotkey is pressed if there is not already a copy of the program being executed. If a copy of the program is already being executed, then the hotkey will merely move that copy of the program to the top of the pile so that you can access it (it will PICK the program and execute a WAKE event, if supported by the program - a Wake event is normally used by a program to force it to update its tables etc).

The second variant of this command was introduced in v2.24 of the Hotkey System II and allows you to specify a name of a job (Wakename$) which is to be woken up if there is already one copy of the original program running in memory. Unfortunately this variant acts differently from the first in one main way:

  • If the original program is already running, and Wakename$ points to another program which is not yet running, a second copy of the original program will be started up.


The following line will allow you to set up the <ALT><R> key to do one of two things:

  • If a job called QR-Config is running already, this will be Woken; otherwise;
  • A copy of a program called flp1_Route_Obj will be started up (even if one is already running).
ERT HOT_CHP1 ('R','flp1_Route_obj';'flp1_\' ! 'QR-Config')


On early versions of the Hotkey System II, HOT_CHP1 did not create an Executable Thing.


Versions of the Hotkey System pre v2.21 do not allow you to pass a command string.


See HOT_CHP. HOT_PICK allows you to set up hotkeys to PICK a program, and HOT_WAKE allows you to set up hotkeys to WAKE a program. HOT_THING allows you to call an Executable Thing.
