I created a trivial gfn that produces a matrix with a NaN in it, then ran a script that calls it, as follows: include ./warntest.gfn nulldata 10 set verbose off matrix M = myfun() print M In this case I saw the message In regard to function myfun (package warntest): Warning: generated non-finite values However, if I inserted "set warnings off" in the caller that suppressed the message. So I'm not sure what's happening in your case. Could you perhaps send me a caller for johansensmall.gfn that provokes a warning?
