Answers.Text: "Computer Notation" is where you record a move just by specifying the piece's original square and destination square - for example, instead of "1. e4" you might write "1. E2-E4".  Instead of "2. Nf3", you might write "2. G1-F3".  And so forth.

Answers.Text: @patbarron Thanks, They did not officially define it. Even then, that is basically a long-form of algebraic, and thus, they still so not all the ICCF's notation.

Answers.Text: FIDE allows the use of the native language abbrev for the piece being moved.   Why not say my language is the two digit home square?  Would FIDE really object to that??

Answers.Text: OTOH, [that FIDE document linked](http://old.fide.com/fide/handbook.html?id=208&view=article) seems to allow recording both the start and the ending squares of a move (C.8 Each move of a piece is indicated by the abbreviation of the name of the piece in question and the square of arrival. [...] A longer form containing the square of departure is acceptable. Examples: Bb2e5, Ng1f3, Ra1d1, e7e5, d2d4, a6a5.) That's not the same as numeric notation but should be equally unambiguous.

Answers.Text: @ilkkachu The first part of the rule is very clear: Only algebraic. That you can use long form is just a footnote overall.

Answers.Text: @PhishMaster, well, unless there's something there that's not obvious to someone not a priori familiar with the FIDE rules, 8.1.1 seems indeed to say algebraic notation is required. Then C.8 defines that the long form is an acceptable form of algebraic notation.

Body: <p>ICCF uses pure numerical notation counting each square by row and column  eg  11 to 88.  So Pd4 often written just d4 -  would be 2224 so there can never be any confusion should two pieces be able to move to the same square. </p>

  ICCF uses pure numerical notation counting each square by row and column eg 11 to 88. So Pd4 often written just d4 - would be 2224 so there can never be any confusion should two pieces be able to move to the same square.
  
  If One used that notation in an OTB tournament would FIDE accept it or would that be a problem?
