Hi Gretl users,
The following code is not working in the new version of
Gretl-2025b. But when I use the previous version of the Gretl it gives the results. What
is the problem with the following code? What is the solution to this problem?
string F_Bound_LS= sprintf"F_Bound_Calculated : %.4f\n F_Lower_Bound_I[0]: %.4f\n\
F_Upper_Bound_I[1]: %.4f\n",F_Calc_Bound_LS, F_B_I0,F_B_I1)
This statement produces an error in the previous two versions of
gretl, 2025a and 2024d, with the same message as given by gretl 2025b,
namely
'sprintf': no argument was given
That's because every gretl function requires an "argument" clause
(even if it happens to be empty, which is permissible in a few cases)
and that clause is identified by an opening left parenthesis "(" and
closing right parenthesis ")". In your statement there's a trailing
right parenthesis but no opening one. So gretl doesn't detect any
argument for the function. I'm confident that the statement as shown
above would not work in any version of gretl.
At one time (prior to gretl 2023c) there was a "command" (as opposed
to function) version of sprintf which did not require parentheses, but
that had a different syntax and the statement above would certainly
not have worked with it.
