[Gretl-devel] About Package: yahoo_get 3.9 (2026-01-20)

Hi, There appears to be a strange error related to the function package GUI in *Package: yahoo_get 3.9 (2026-01-20)* for *gretl 2026a*. When I run the following script, everything works correctly: nulldata 1000 setobs 5 2022-06-01 # a daily dataset should already be in place delete index series apple = yahoo_price("aapl") # get Apple, adjusted price only list L = yahoo_full("msft") However, when I access the same functionality through the GUI (as shown in the attached file), I receive the error message: *"Argument 1 (ticker) is missing."* I conducted quick tests on versions *2025a* and *2025b*, and no such error occurred. However, version *2025c* also produces the same error message: *"Argument 1 (ticker) is missing."* Is there something changed since the version 2025c? best regards, Yi-Nung [image: 57b76909-1030-49ba-a64e-48ad4442e72d.png]
