st: RE: RE: tabodds command with 'if' option

Note that -For- is not a Stata command. The command is -for-. Also, unless the user has an old version of Stata, no on-line help is now available for -for-.

For reasons documented elsewhere, -for- is in essence deprecated. -forval- and -foreach- should be considered preferable.
