TeXbyTopic¿¡ ¾²¿©Á® Àֱ⸦, Anyone who has ever browsed through either the plain format or the LaTeX format will have noticed that a lot of control sequences contain an 'at' sign: @. These are control sequences that are meant to be inaccessible to the ordinary user. Near the beginning of the format files the instruction {{{ \catcode¡®@=11 \}}} occurs, making the at sign into a letter, meaning that it can be used in control sequences. Somewhere near the end of the format definition the at sign is made 'other' again: {{{ \catcode¡®@=12 \}}} Now why is it that users cannot call a control sequence with an at sign directly, although they can call macros that contain lots of those 'at-definitions'? The reason is that the control sequences containing an @ are internalized by TeX at definition time, after which they are a token, not a string of characters. Macro expansion then just inserts such tokens, and at that time the category codes of the constituent characters do not matter any more. TeXbookÀÌ ¸»Çϱ⸦,
