[Gretl-users] Some errors in User-defined functions
Dear all,
I tested the User-defined functions and found some potential errors.
For example, my function is:
<script>
function test (series y, int order[0:2:1], string option[null])
if option="nc"
printf "%s\n","empty"
else
printf "%s\n","no options"
end if
end function
</script>
the argument, string option[null], above should indicate that the
"option" string should be optional.
After normally processing it as a package, I execute this function via
GUI (the same via command line). If I choose the default "null" as
automatically specified by gretl, I got an error:
"The symbol 'otion' is undefined... error evaluating 'if' "
If I type any other strings, it works as normal.
If I give no string at all in the text box, gretl tells me:
"Argument 3 (option) is missing"
I also test it in the command-line console, for example,
? test(djclose,1,"nc")
empty
? test(djclose,1)
The symbol 'option' is undefined
error evaluating 'if'
? test(djclose,1,"1")
no options
Are these normal or potential bugs?
