The source code in this repository was digitized manually from paper printouts, so typos and other discrepancies have been introduced accidentally. The code shall be modified to be made consistent with the scanned printouts:

Useful Extensions

GitHub has syntax support for the AGC assembly language built-in. Unfortunately your code editor will not, however there are AGC language extensions that provides syntax highlighting for the following editors:

† Supports automatic formatting

Formatting

Note: GitHub and extensions marked above will ensure you're using the correct formatting automatically.

  • Use tab indentation
  • Use tab width of 8
  • Trim trailing whitespace

What do I check?

Any discrepancies between the scans and the source code in this repository, including:

Comments

  • Comments in the transcribed code should match the scans exactly
    • This could involve creating a deliberate typo or removing/adding an entire comment.

Line breaks

  • Line breaks with R0000 in column 1 should match the scans exactly.
  • Line breaks with*out* R0000 in column 1 should contain only 1 or 2 blank lines in a row.
    • If there are more than 2 blank lines breaks, strip the extra line breaks.
      • Lines with R0000 in column 1 do not count towards this.
    • In the source images, these were created by an unprinted digit in column 8. A 2 there forced a double space (single blank line) and a 3 forced a triple space (double blank line). Values 4-8 were defined but never used. Read more about it in #159

For example the following:

R0819   SUBROUTINE TO SKIP...
R0820



 0821   LAMPTEST  CS  IMODES33

Should become:

R0819   SUBROUTINE TO SKIP...
R0820


 0820   LAMPTEST  CS  IMODES33

Spaces

  • Spaces between two characters in the string should respect the following convention (see the discussion in #316):
    • Single space for new words.
    • Double space for new sentences.
    • Triple space for indentations.

For example the following:

	1)  FOO BAR BAZ QUX QUUX QUUZ. CORGE, GRAULT,
	GARPLY, WALDO.

Should become:

	1) FOO BAR BAZ QUX QUUX QUUZ.  CORGE, GRAULT,
	   GARPLY, WALDO.

Note

Before you make a PR, please make sure your changes are consistent with the scans!
