No. Belay that. I don't understand your example and your rule now that I
look at it again.

Subject: st: RE: Deleting Characters of a Var Name by index Number
What you want may be called a macro in other languages, but it is not in
Stata.
There is no need to write any new command, program or do file.
foreach var of var <whatever> {
local newvar = substr("`var'", 1, length("`var'")-2) +
substr("`var'", -1, 1)
rename `var' `newvar'
}
Alternatively, check out -renvars- (-search- for locations). Use the
-map()- option.

I would like to write a macro that renames variables by deleting a
specific
character of a variable name for a group of variables.
For example, suppose that I have variables X31 X42 X53 and so on. I
would
like to wite a macro that does something like the following:
foreach var of varlist X31 X42 X53{
rename `var' = [X and only the second to last character from the
*left*
of `var']
}
That is, X31 would then be renamed X1 and X42 would be X5 and so on.
