st: inputting data via a series of nested loops

Hi all,
I am trying to encourage Stata to enter data into a new dataset via a loop
in an ado file. I was not able to find anything in the archives that fit my
situation (though I did find this:
http://www.stata.com/statalist/archive/2010-07/msg00425.html).
For example, say I wanted to end up with this as my dataset:
type place time
a 1 1
a 1 2
a 2 1
a 2 2
b 1 1
b 1 2
b 2 1
b 2 2
c 1 1
c 1 2
c 2 1
c 2 2
I have tried the following which works:
local name "a b c"
foreach n of local name {
forvalues time = 1/2 {
forvalues place = 1/2 {
display "`n' `time' `place'"
}
}
}
end
*
The results:
. do "B:\temp\STD08000000.tmp"
. local name "a b c"
. foreach n of local name {
2. forvalues time = 1/2 {
3. forvalues place = 1/2 {
4. display "`n' `time' `place'"
5. }
6. }
7. }
a 1 1
a 1 2
a 2 1
a 2 2
b 1 1
b 1 2
b 2 1
b 2 2
c 1 1
c 1 2
c 2 1
c 2 2
And therefore I hoped the following would work:
input name time place
local name "a b c"
foreach n of local name {
forvalues time = 1/2 {
forvalues place = 1/2 {
`n' `time' `place'
}
}
}
end
*
But, for which I get:
. do "B:\temp\STD08000000.tmp"
. input name time place
name time place
1. local name "a b c"
'local' cannot be read as a number
1. foreach n of local name {
'foreach' cannot be read as a number
1. forvalues time = 1/2 {
'forvalues' cannot be read as a number
1. forvalues place = 1/2 {
'forvalues' cannot be read as a number
1. `n' `time' `place'
'`' cannot be read as a number
1. }
'' cannot be read as a number}
1. }
'' cannot be read as a number}
1. }
'' cannot be read as a number}
1. end
. *
.
end of do-file
Any ideas how to correct?
Thanks, in advance,
Ben
