st: RE : st: RE : st: RE : st: Do-file no result, command line OK

[<X.Y.Vollenweider@lse.ac.uk>]

I reproduce below two do-files which are similar to mine. The first one works fine, we get rid of the dot. However, the second one, which differs from the 1st one just because a command line has been added, doesn't work any more. This the thing I do not understand.

*** Option 1 
sysuse auto
global variables make			// I have two variables in the original do-file
foreach var in $variables {
gen `var'_2 = subinstr(`var', " ", "", .)
replace `var'_2= subinstr(`var', ".", "", .)
}


**** Option 2
global variables make			// I have two variables in the original do-file
foreach var in $variables {
gen `var'_3 = subinstr(`var', " ", "", .)
replace `var'_3= subinstr(`var', ".", "", .)
replace `var'_3= subinword(`var', "Chev", "", .)
}
browse

That does not make sense.

... if variable == "."

can't be satisfied by values such as "BP P.L.C." as they are not equal to ".".

Either you mean something else, or your copy of Stata is hopelessly corrupted.
