st: to replace just one character of values of a variabl

Hello people,
 
I imagined that a variation of the same command 
*****
drop if strpos(mystrvar, "`=char(191)'")!=0
*********
 could be used to replace just one character of values of a variable.

I tried this but didn't function

*****
replace if strpos(var1, "`=char(64)'")!=0
*********

Please Help me!

 
Thanks Carmen

Stata will delete those happily if you find a way to tell it what to -drop-.
In this case, -ssc d asciiplot- by Nick Cox tells you which number to pass
to -char()- to check for the presence of the character:
 
*******
clear*
 
inp str10 mystrvar
"hello"
"goo¿d-bye"
"he¿lo"
"goo¿d-bye"
"hello"
"hello"
end
 
list, noo
 
drop if strpos(mystrvar, "`=char(191)'")!=0
 
list, noo
*******

hello people,
 
 
Another question, stata could delete
all the row of a variable containing characters like
"¿", for example.
 
 
Thanks Carmen
