Naming the substitution

AsTeR chooses identifier names that convey some information about the object being replaced. This has two advantages:

Names for the substituted expressions are chosen using the following information:

Thus, when substituting for the subscript to a summation operator, AsTeR uses the name ``lower constraint''. Since more than one such ``lower constraint'' may be substituted in a general expression, such names are appended with an integer to make them unique. This is how the rendering shown earlier for Faa De Bruno's formula is produced.
