g codes of the rs274/ngc language are shown on a specific page each the descriptions contain command prototypes, formatted as a code block in the command prototypes, three dots … substitute a real value as described earlier, a real value may be (1) an explicit number, 4, for example, (2) an expression like \[2+2] , (3) a parameter value, #86 , for example, or (4) a unary function value like acos\[0] in most cases, if axis words (any or all of x… , y… , z… , a… , b… , c… ) are given, they specify a destination point axis numbers are in the currently active coordinate system unless explicitly described as being in the absolute coordinate system where axis words are optional, any omitted axes will have their current value any items in the command prototypes not explicitly described as optional are required it is an error if a required item is omitted in the prototypes, the values following letters are often given as explicit numbers unless stated otherwise, the explicit numbers can be real values for example, g10 l2 could equally well be written g\[2 5] l\[1+1] if the value of parameter 100 were 2, g10 l#100 would also mean the same using real values which are not explicit numbers as just shown in the examples is rarely useful if l… is written in a prototype the … will often be referred to as the "l number" similarly the … in h… may be called the "h number", and so on for any other letter g code meaning g0 (rapid linear motion) docid\ smeipmfnlzqwnk8pfsszc rapid positioning g1 (linear motion feed at feed rate) docid\ riq0kxply7lfjpieik24b linear
