Abstract
Source code including application defined expressions and non-conforming identifiers are compiled to executable code. The source code is written with an application defined expression or non-conforming identifier enclosed between a predefined pair of matching separators, such as square brackets. When a sequence of characters between the predefined separators is encountered in the source code during compiling, a symbol table is searched for a matching identifier. If found, the characters are interpreted as a non-conforming identifier and bound to the matching identifier. If not found, the characters are interpreted as an application defined expression and bound to a function call for an evaluating function provided in an application library.
