IT LOOKS COMPLICATED: BRACKETS OR BRACES INSIDE MORE BRACKETS OR BRACES It's called "nesting", but it's not really so difficult THE RULES ARE BASICALLY SIMPLE Is it a variable or a KEYWORD? Is it inside or outside a [ ] or a { }? Is the punctuation that goes with it inside or outside the [ ] or { }? [A[,B]] NESTED A and B are parameters of some command. ,B BRACKETS nests inside A. A is optional--use it if you want. Use A and you can also use ,B. If you don't use A, you can't use ,B. [A] STACKED A, B, and C are all optional parameters of [B] BRACKETS the command. You can choose NONE of them [C] or ONE of them -- but NO MORE than one. {A} STACKED A, B, and C are parameters of the command. {B} BRACES The braces tell you that you MUST pick and {C} use one...but ONLY ONE. ...Please pressBack to Main Index
