Source Code

These source-code files were transcribed from the attachment of issue #13 of the AGC Information Series, "YUL Programming System" (1963). It is a tiny sample Block I AGC program for demonstrating the usage of the YUL assembler, as well as the encoding of the punch cards, and the error handling of the assembler.
Scans of the assembly listing of the program can be found at the Virtual AGC project website, and the full document can be found in the Virtual AGC document library.
