st: expanding numlist |

Dear listers, I have two variables: groupid and list. "groupid" identifies the group and "list" is numeric list of members. For example: groupid list 1 3 8 9 10 2 5/9 11 23/27 3 6 7/10 ... ... Now "list" is always a valid numlist (because I entered it as such). I want to get this data into a long format (i.e. expand "list" for each "groupid"). But I'm having troubles from the start, I can't even get Stata to read in each observation of "list" as a numlist. For example I tried the following piece of code. count local end = r(N) forvalues i=1/`end' { local numbers "list[`i']" foreach n of numlist `numbers' { di `n' /*just to test if this works*/ } } this gives me an error: invalid numlist Setting the trace on, I see that foreach n of numlist `numbers' { is processed as foreach n of numlist list[1] { which is clearly an invalid -numlist- However, when I try this: count local end = r(N) forvalues i=1/`end' { local numbers "list[`i']" di `numbers' } I get a list of all the observations in "list", so `numbers' is being read as the content of list[`i']. So I am puzzled why `numbers' cannot be read as a -numlist- So my direct question is how to read in "list" as numeric list. I think once I do this I can manage to do my reshape.
