Problems with Tutorial

I have been attempting to learn SKILL by following a tutorial I found at referencedesigner.com I've copied the instructions from the tutorial below and when I attempt to run the command I get the following message: Command > formbutton

E- *Error* axlFormDisplay: argument #1 should be any user-defined (other) type (type template = "o") - nil Can anyone explain what might be wrong? Thanks in advance.

SKILL code tutorial begins here :

Allegro SKILL Tutorial | Forms

Copy the following code in a file form.il and save it in the directory C:/cadence/setup/skill (or the directory that allegro.ilinit points to).

 
axlCmdRegister( "formbutton" `formbutton)
; -----------------------------------------------------------------
procedure( formbutton()

	les1_form = axlFormCreate( (gensym) "les1.form" nil 'les1_form_Action t)
	axlFormDisplay(les1_form)

); end of procedure
; -----------------------------------------------------------------
procedure( les1_form_Action(les1_form)
	case( les1_form->curField

		("Close_button"
        	axlFormClose( les1_form )
		 	axlCancelEnterFun( )
      	); --------------------------

 		("Run_button"
			if( axlFormGetField( les1_form "report") then  
				axlUIConfirm( "Report value is t (True) ")
			else
				axlUIConfirm( "Report value is nil (False) ")
			); end if
			
      	); --------------------------	
	); end case
); end of procedure
; -----------------------------------------------------------------

What does this skill code do

There are four axl statements for the form

axlFormCreate - Creates a Form
axlFormDisplay - to Display the form
axlFormClose - to Close the form 
axlFormGetField - retrieve the elements in the form

Other code should be easy to follown.
Now creat another file called les1.form with the following content

 
FILE_TYPE=FORM_DEFN VERSION=2
FORM
FIXED
PORT 25 20
HEADER "Referencedesigner.com"

TILE
#======================
FIELD report
FLOC 2 2
CHECKLIST "Create report"
ENDFIELD


FIELD Run_button
FLOC 2 17
MENUBUTTON "Run" 7 3
ENDFIELD

FIELD Close_button
FLOC 11 17
MENUBUTTON "Close" 7 3
ENDFIELD

#======================
ENDTILE

ENDFORM

Save the file in the same directory as you brd file. Assuming everything is right you can just type hello form at the Command and it will pop up a form.

Did you save the form in the same folder as your brd file? Check also that the name of the form matches exactly the one in the axlFormCreate line of the code.

Saving the form in the same directory as my board file was the trick. Thanks, Dave. You're the best!!

Hi,
Allegro looks at for configuration files in the following default locations:
Cadence provided default configuration files: <cdsroot>/share/pcb
Site (company) provided location (this is called CDS_SITE):<cdsroot>/share/local/pcb
see attached PDF

BR,
