When you enter the Equation Catalog, the 48 lists all variables in the current directory that are algebraics or that have names ending in "EQ". This allows you to include objects other than algebraics in the catalog. The 48 assumes that when you press NEW, you are presenting something you wish to see in the Equation Catalog. Therefore, if it is not an algebraic, the 48 automatically places ".EQ" in the command line for you, as a convenience. The cursor is positioned before the ".EQ", so any characters you type appear before it. The "." is not necessary but is used to make the name look nicer. If you don't enter any characters, you get invalid syntax because variables names cannot begin with a period. You must type at least one letter, like "A" to get "A.EQ". -- edp
