Plenty, but please provide more details on what you are doing. Capture protects a certain section of your program, that section is treated as one unit, it either works or not(*). If your program (do-file) has structure P=A->B->C and B may potentially fail with an error and you want C to run anyways, than B should be wrapped in -capture-, not the whole A->B->C. However if C depends (!) on the results obtained in B, then if B fails there is no point in running C, and the whole A->B->C should be wrapped in -capture-. Which one is your case - I don't know. Consider the following examples: if after estimation of a model you estimate a different model, or try a different estimation strategy of the same model, then you do want that part to run regardless of the success in the first one. Then use -capture- around the first part only.If after estimation of model you want to do a prediction, then the prediction naturally depends on the results of the model estimation and should not be done if the model is not estimated. Best, Sergiy Radyakin (*) unless it contains -capture- within, then it gets more complicated > > Thanks, > Katia > > 2010/10/26 Sergiy Radyakin <serjradyakin@gmail.com>: >> Sure there is an alternative: >> >> 1) runs the same file 10 times with different parameters: >> >> forvalues i=1/10 { >> capture noisily do "C:\PROGRAMS\mydofile.do" `i' >> } >> >> Runs mydofile.do 10 times, tolerating errors in each run-iteration. >> Value of i is passed as a parameter. >> Depending on what you are doing, you may want to form the actual >> parameters outside and pass to the >> do-file or inside of the do-file, based on the iteration number. >> >> Remove -noisily- if you do not need the output of individual iterations. >> >> 2) runs 10 do-files one time each: >> forvalues i=1/10 { >> capture noisily do "C:\PROGRAMS\mydofile`i'.do" >> } >> >> (files must be named mydofile1.do, mydofile2.do, etc) >> >> Best, >> Sergiy Radyakin >> >> >> >> >> On Tue, Oct 26, 2010 at 2:32 PM, Katia Bobulova >> <katia.bobulova@googlemail.com> wrote: >>> Dear Neil, >>> >>> thank you very much for your answer.
