How to double quote the double quote

[Chen Samulsion]

Dear Stata users,

I have a string variable that some values of it are leading by a double quote ("). I want to trim the leading double quote using -subinstr()- function. However, I find that I cannot quote the (") in double quote ("").

replace name=subinstr(name,""","",1)

* Example generated by -dataex-. To install: ssc install dataex
clear
input str10 name
"John"    
`""Lee"'  
"Richard"  
`""Smith"'
`""Alfred"'
"Grusky"  
end

The -dataex- result has provided me hints. I should use compound double quotes.

replace name=subinstr(name,`"""',"",`)
