Pulse Assembler

Assembler: a low-level programming language for a computer, in which there is a very strong correspondence between the language and the architecture's machine code instructions.

Virtual machine: an emulation of a particular or hypothetical computer system.

SpecMan4EPR Assembler is executed on the Virtual Machine that has two registers: ax register, internal time counter register treg, and the stack. The Assembler supports memory addressing, conditional statements, cycles and jumps. To reduce the length of program, many assembler commands perform composite actions.
