    Abstract:
    During the development of programs for a high-speed biomedical data acquisition system, a need arose for the precision and efficiency of assembler language and the clarity and programming simplicity of higher level control structures. A set of macros was written to augment the assembler language for the DEC PDP 11 computer to provide simplified forms of the control structures of Pascal. IF, FOR, WHILE, REPEAT/UNTIL, CASE, and subroutine facilities are present. The control structures are fully nestable. IF and WHILE may be augmented by use of the logical operators OR and AND. The method of implementation of the control structures is relatively simple. Similar control structures could be implemented on other macro assemblers which allow certain basic operations
