Function Names
depthDescription
The function depth() returns the nesting depth of a specified variable. 1 is returned for all variables not containing any array or
structure members. 2 is returned if one level of members, e.g. a simple array or structure without nesting is provided. 3 is returned if
further sub-members are specified, and so forth.
The function weight profile provides more detailed weight information for every level in the variable tree. The base variable is
level 0, its array and structure members are at level 1, their sub-members at level 2, etc. The value returned is a set containing
the weight fore every level found.

Examples
dim( a[], 10, 0 ); // Level 1
dim( a[3], 5, 0 ); // Level 2
structure( a[3,2], { Ha, He, Hi, Ho }, { 1, 2, 3, 4 } ); // Level 3
echo( "Variable a[] : ", depth(a[]), " The entire variable tree" );
echo( "Variable a[1] : ", depth(a[1]), " Member variable of a[], but has no sub-members" );
echo( "Variable a[3] : ", depth(a[3]), " This one has sub-members" );
echo( "Variable a[3,2]: ", depth(a[3,2]), " This variable contains 4 leaf variables" );
echo( "Variable a[3,2,Ha]: ", depth(a[3,2,Ha]), " This leaf variable has depth 1 (no further variables)" );Output
Variable a[] : 4 The entire variable tree
Variable a[1] : 1 Member variable of a[], but has no sub-members
Variable a[3] : 3 This one has sub-members
Variable a[3,2]: 2 This variable contains 4 leaf variables
Variable a[3,2,Ha]: 1 This leaf variable has depth 1 (no further variables)
