Subject | st: Postfile "forgets" the postfile |
Date | Thu, 24 Feb 2011 02:21:16 +0100 |
Hi, at some point in my code i define a postfile, in which i want to write 4 variables, say one two three four. . postfile x one two three four using somedataset, replace then open a forval loop and after some calculations i want to add new observations to the postfile, using the code: . post y (one) (two) (three) (four) unfortunately, at this point stata tells me: post x not found r(111); So apparently, Stata lost the postfile definition along the way somehow... I could track down the exact point at which Stata lost the information, which is a selfwritten ado. So the problem lies probably in the ado. I suspect the preserve / restore / clear combination i use in there. I am not an experienced ado writer, so please help me. the simplified structure of the ado is like this: program tuples2, rclass version 9 syntax varlist(min=1 max=1 numeric) [if] [in] .... preserve clear set obs2 .....do some stuff .....write the results i am interested in into return macros restore end Could this "clear" be responsible for the damage? If yes, is there another way I can "start from scratch" in the ado file (and in the end restore the damage done) while NOT hurting the postfile definition? Thanks for a little help.
