1959 E. M. Grabbe et al. Handbk. Automation, Computation, & Control II. ii. 254 Many macroinstructions can be constructed from properly sequenced microinstructions.

1959 Jrnl. Assoc. Computing Machinery 6 132 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.].

1961 Times 3 Oct. (Computer Suppl.) p. x/5 Through the use of these macro-instructions the computer can be given the semblance of being a much more powerful machine than it really is.

1970 O. Dopping Computers & Data Processing xix. 312 By introducing macro instructions in the source language, the designer can bring about the same ease of programming as could be achieved by giving the computer a more powerful operation list than it really has. But naturally, one does not get the same advantages in terms of economy of memory space and computer time as would be obtained if the more powerful instructions were really built into the machine.

1980 C. S. French Computer Sci. xxv. 194 A macro instruction is a single instruction written as part of the source program language which when assembled will generate many machine code instructions.
