for George INput

Special-purpose macro assembler used to build the GEORGE 3 operating system for ICL1900 series machines.

A macro could examine the assembly process and possibly modify its further course.

from the 1900 languages page

GIN - George INput was a special assembler language used for writing the Operating Systems and Executives (GINX). Syntactically it was similar to PLAN, but had many more features. Unlike PLAN, it was not a compiler but an assembler that was complete in itself and could not be mixed with other languages.
