10.36.2.6 Name Auto-Generation

There are two cases when a name is automatically generated.

1. When a name is assigned to a compound term by the user, each variable appearing in it is assigned a so called derived name, which is created by appending a variant of the selector of the variable to the original name. For example, the call:

             fdbg_assign_name(bar(A, [B, C], foobar(D, E)), foo)
        

   will create the following name/term entries:

   Name	Term/Variable	Selector
   foo	bar(A, [B, C], foobar(D, E))	[]
   foo_1	A	[1]
   foo_2_1	B	[2,#1]
   foo_2_2	C	[2,#2]
   foo_3_1	D	[3,1]
   foo_3_2	E	[3,2]

   See FDBG Naming Terms.

2. If, during the annotation of a term (see FDBG Annotation) an unnamed constraint variable is found, it is assigned a unique “anonymous” name. This name consists of the prefix `fdvar', an underscore character, and an integer. The integer is automatically incremented when necessary.
