Open (run, launch) program (a single .exe file) using form button (SKILL Cadence).

I would like to open calculator (a single .exe file) using the form button.

i.e: I need to assign the calculator (stand alone) program to one of the form buttons.

I have my form built already, don't know the axl.... command yet.

Used the template below, but can't figure out what "Handle" means (MyFormHandle) and what exactly to type..

I tried to use this code with my working form which uses (gensym) method, but got lost.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

axlFormCreate takes a global symbol as its first argument.
Many programmers use the Skill’s ”gensym” function to dynamically generate a
symbol. If you want only a one instance of the form open then it is better to ICU 2004 13 use a global symbol. The following template shows how a form should be opened.  If you make MyFormHandle a local variable, instead of global and then invoke Skill’s garbade collector via the “gc” call form will close.

; NOTE: Change all instances of the “MyForm” prefix to the prefix
; you plan on using for your program.
;; init global form handle to nil

unless(boundp(MyFormHandle) MyFormHandle = nil)

;;
;; This is a good example on how to program a form.
procedure( MyForm(fw)

prog( (position) ; need to do this since have a return
;; Good pratice, if form is open expose it and return
(cond (fw
(axlUIWExpose fw)
(return fw)
)
)
position = '("CENTER" "msglines" 1)
;; create a form handle, position form and set-up mode
fw = axlFormCreate('MyFormHandle "MyFormFile" position
'MyFormCallback t nil )
; Initialize the fields in the form
MyFormUpdate(fw)
;; Last thing to do is display the form
axlFormDisplay(fw)
)
)

So, two questions:

1. Open calculator using form button

2. Keep only one instance of the form on the screen.

Thanks you genius.
