1959Jrnl. Assoc. Computing Machinery VI. 132 The built-in system macro instructions in Scat presently consist of (1) two macros for generating the..standard entry and exit from subroutines, (2) a set of debugging macros [etc.]. 1961Leeds & Weinberg Computer Programming Fund. iv. 103 The assembly program can be instructed to recognize this instruction sequence through the use of a single form called a macro-instruction... Recognition of the ‘macro’ form causes the assembly program to assemble the corresponding sequence of one or more machine instructions. 1963L. Schultz Digital Processing xi. 240 To avoid having to write the groups repeatedly, the programmer..instructs the machine to establish a table in which it stores the group of instructions. To identify the group, he assigns a code name, called a macro name. Ibid., The programmer writes one instruction (a macro) and the machine ‘generates’ several. 1966New Scientist 27 Oct. 162/3 In the ICT command language it is possible to define new commands in the language in terms of those already defined. An example of this ‘macro’ facility is given here... The effect is to allow the user to condense a long and complicated job description into a shorthand phrase of his own choice. The use of ‘macros’ in this way makes it extremely easy for the user to set up his own conventions. 1970O. Dopping Computers & Data Processing xix. 324 As an advantage of automatic coding, it is sometimes pointed out that the macros and subroutines are tested and error-free, in contrast to home-made subroutines. 1972J. J. Donovan Systems Programming iv. 111 In employing a macro, the programmer essentially defines a single ‘instruction’ to represent a block of code. For every occurrence of this one-line macro instruction in his program, the macro processing assembler will substitute the entire block.
