should, almost certainly, be understood
in context. It will be part of a preamble 
that parses what the user types, all 
preparatory to a -parse- which brought 
everything together. 

Here is an example of what we used to do 
("those were the days, my friend", etc.): 

    local varlist "req ex"
    local if "opt"
    local in "opt"
    parse "`*'"

In current Statas, this would be done 
this way: 

syntax varlist [if] [in] 

Thus, in short, 

local if "opt" 

is equivalent to part of a -syntax- command, 
but only as a part of a sequence of statements.
