Problem creating an inline form

Question

Hello, 
 2 years ago I created an inline form that worked pretty well. You can find it here : github 
 I am trying to create another skill program using an inline form base on the code from the example above, but it doesn't work well . 
 
 Here is the code :

; skill load "EasyDD.il" axlCmdRegister("easydd" 'EasyDD) unless(boundp('formHandle) formHandle = nil) 
 inLineForm = '(" FILE_TYPE=FORM_DEFN VERSION=2 FORM FIXED PORT 61 300 HEADER \"EasyDD\" TILE TEXT \"Numero CIU :\" TLOC 3 3 ENDTEXT FIELD ciuNumberFillin TLOC 22 3 STRFILLIN 35 200 ENDFIELD FIELD close FLOC 20 40 MENUBUTTON \"Close\" 10 3 ENDFIELD ENDTILE ENDFORM ") 
 procedure( EasyDD() let(() ; CREATE AND DISPLAY THE FORM eddForm = axlFormCreate('formHandle list("myform" inLineForm) list("center") 'EasyDDCallback t nil) axlFormDisplay(eddForm) axlFormSetField(eddForm "ciuNumberFillin" "tt") )) 
 procedure( EasyDDCallback(eddForm) let(() case( eddForm->curField ( "close" printf("EasyDD closed.") axlClearSelSet() axlFormClose(eddForm) axlShell("done") ) ;case "close" ) )) 
 ;EasyDD()

The STRFILLIN object I use is not displayed. I have tryied moving it to the right. I have tried pre-filling it using axlFormSetField, but it just does not appear. 
 I have set a window size of 61x300, but the window just doesn't have this size, it is much smaller... What is the point of specifying a size ? If I put the "close" button at x400, it does not limit the size of the window to x61... 
 I don't understand how this function work : eddForm = axlFormCreate('formHandle list("myform" inLineForm) list("center") 'EasyDDCallback t nil). I have read the manual (algroskill.pdf) but it is not very clear. What does 'formHandle means ? The manual says it is a "Global SKILL symbol used to reference form". What is a symbol ? Can I put whatever I want here ? If I open my other form program after loading this one, it does not use the correct form (it is using the one from the previously loaded .il file). I suspect it to be due to this formHandle thing. But even if I change formHandle to, let's say, formHandle2, the form used is the same... What are the list used for ? What is "myform" ? Why list("center") ? So much questions :D 
 
 Thank you in advance :) 
 By the way, I am using OrCAD PCB Editor Pro 17.4

When I try running your code it crashes Allegro, I haven't been able to isolate the cause yet, but below are a few answers to your basic questions... 
 I would recommend you spend more time reviewing the 'Cadence SKILL Language User Guide' and the 'Cadence SKILL Language Reference' documentation; 
 What is a symbol? page 97 of 'Cadence SKILL Language User Guide' states "Symbols in SKILL correspond to variables in C." 
 In your code the entry at the top of the file initializes that symbol: unless(boundp('formHandle) formHandle = nil) 
 However to avoid name clashes I have found using gensym() to create a unique symbol name reduces errors, an example is shown below: 
 (LBRN_WriteEDIF_Form = (axlFormCreate gensym() LBRN_outFormFile list(e outer) 'LBRN_WriteEDIF_Form_Action_Routine t)) 
 What is "myform"? It's the name of the form file to load, however the inLineForm data provides the data without loading an external form file. 
 The 'list("CENTER") is the Optional form placement. Allegro uses its default placement if this argument is nil. 
 in my example shown above it's list(e outer)
