Com (from Latin Comma - comma)
In programming, the word "com" usually refers to two punctuation marks (semicolon and comma) that are not used in English. They look like this: ";" (semicolon) and "," (comma). If you look at programming languages: for example, you can see that languages program programmers from the point of view of their psychological impact on people. So, if on the sign “;” do not make a large indent, then the sign will be perceived in combination with the preceding phrase as a comma with negation, or as a subordinate clause
