I am pretty sure there are easier ways to do what you are trying
(generating dummies using some kind of -xi- and then retrieving the
logical conditions which generated those conditions using the
auto-generated variables names), here is some code that does what you
want:
*-----------------------------------------------------------
local dumnames
forvalues i = 1/10 {
local dumnames "`dumnames' _Iphstat_`i'"
}
di "`dumnames'"
foreach x of local dumnames {
if regexm("`x'", "^_I([A-Za-z0-9-]+)_([0-9])$") {
local dumcond`i' "`=regexs(1)'=`=regexs(2)'"
di "`dumcond`i''"
}
}
*-----------------------------------------------------------
You should be able to make this code much more compact by getting rid
of the loop.
