Why do you want to -generate- a new variable which is supposed to hold a single string? And what is "p"? If it is a variable, as your -while- loop suggests, then Stata automatically picks the first observation to evaluate whether the -while- loop should run or not. I have a feeling that is not what you want...

Subject: st: programming loop local question


I´m automating a bar graph program with ci and everything is working
out allright except for this loop and local variable that I cannot
figure out.
.....bunch of stuff first
local r=0

while p+1>`r'{
gen e`r'="(bar gcs m if `2'==`r') "

local list `list' e`r'
local r=`r'+1
}

tw `list' (rcap higcs logcs m)


and I get :

invalid 'e1'
r(198);



Error searching with a display of the local :

local r=0

while p+1>`r'{
di p
di `r'
gen e`r'="(bar gcs m if `2'==`r') "
di e`r'
local list `list' e`r'
di `list'
local r=`r'+1
}

tw `list' (rcap higcs logcs m)

(bar gcs m if maxaisorgansystemhead==0)
(bar gcs m if maxaisorgansystemhead==0)

1
(bar gcs m if maxaisorgansystemhead==1)
(bar gcs m if maxaisorgansystemhead==0) (bar gcs m if maxaisorgansystemhead==1)

2
(bar gcs m if maxaisorgansystemhead==2)
(bar gcs m if maxaisorgansystemhead==0) (bar gcs m if
maxaisorgansystemhead==1) (bar gcs m if maxaisorgansystemhead==2)
(bar gcs m if maxaisorgansystemhead==0) (bar gcs m if
maxaisorgansystemhead==1) (bar gcs m if maxaisorgansystemhead==2)
invalid 'e1'
r(198);


I´m sure there is a simple solution but I´ve trying with all sorts of
different " " ´` combinations without getting it to work and the last
display of the local seems to work so I really dont have a clue...
