Abstract: In compiling source code organized in projects, unqualified name references are bound to program objects by searching namespaces in ascending hierarchical order from a current program unit to a current project. Namespaces within projects directly referenced by the current project are then searched. The search is completed at the first namespace in the search order which contains the matching name. Thus, program objects in projects directly referenced by the current project can be referenced by an unqualified name, without import or export lists of program elements.

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.
