Hi, not a bug (perhaps), but a bit strange I think. There was the following sort of mistake in my script: <pseudostructure> x = 1 # scalar ... loop ... catch string x = readfile(...) # string print errmsg($error) endloop </pseudostructure> Gretl correctly complains. However, first the message is something like "unmatched data type" and then switches to the more precise "x is of type scalar, not acceptable". Shouldn't the error message stay the same? What I mean is that it feels like something inside gretl is path-dependent which shouldn't be. This is the Nov 19th snapshot. thanks sven
