Prevent the FD from using the zero value

[Marc56us]

I have been using the FD for years and sometimes I have problems with fonts (a font does not change) or images that are shifted (it is not the right image that is loaded in the first image)
I may review the code line by line, but I never found out why. I think there is a place where the system misuses the value zero

Failing to find out where, I found a trick for: Prevent the FD from using the value zero for each of the enumeration types by using this value for another constant (even if not used)
As the FD code cannot be modified, I create enumerations called before the IncludeFile of forms

Code: Select all

; Main Code

EnableExplicit

Enumeration FormWindow
    #Void
EndEnumeration

Enumeration FormGadget
    #Void
EndEnumeration

Enumeration FormMenu
    #Void
EndEnumeration

Enumeration FormImage
    #Void
EndEnumeration

Enumeration FormFont
    #Void
EndEnumeration

; And then call forms

XIncludeFile "..... .pbf"
XIncludeFile "..... .pbf"
XIncludeFile "..... .pbf"

And it works.
