Complexes in LYaPAS

The changes in semantics of operations over the data structures called complexes in the LYaPAS programming language are discussed. The modifications include resizing the complexes, passing complexes that are created by a callee to the caller, and compile-time error reporting due to modifying operations being applied to input complexes. The goal is to make the work with complexes more convenient and less error prone, which is assumed to have a positive impact on the security of the programs written using the new language constructs. The implementation of the new semantics in the module of the translator is demonstrated.
