Assembler for the KRS 4200 Small Computer System.

The system-oriented programming language and the operation mode of the translation program are explained. The assembler translates the source program, consisting of symbolic machine instructions, pseudo-instructions and control program calls, into a binary symbolic object program which is transformed into a binary absolute for for the processing by a loader. The article deals with the basic course of the two-phase translation and the peculiarities of the division of storage into sectors as a result of the 16-bit machine word.
