Appologies for the typo of the -for- command. (The capitalization results from an "auto-correct" function in my word editor. I catch most, but not all.) More importantly, though, why is the -for- command being dropped? Obviously -forval- and -foreach- are far more flexible, but the -for- command is quite convenient in routine data manipulation and analysis. Its a great way to introduce new students to looping over numbers or variables. I would vote for retaining it.

Subject: 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.
