I keep getting and error message in the following code: And, Bean...what is the latest propbasic version, I should be using?

The error code is:

    As of today's date, the latest PropBASIC version is 1.48

    You will find it attached to the first post in this thread:

    I could verify this issue.

    When compiling, the generated spin file for each task does not include long definition for __InitDirA.
    (main .spin does, but not the tasks)

    @Bean @Mickster Sorry to tag you, but any ideas on what to try? I'm going to grab an older propbasic.exe to test in a moment.

    @denno

    When posting code, could you use the code tags please?
    They make things easier to read, and easier to copy paste your code for testing.

    I've edited you first post to include the tags, so you can see how they work.

    To get the tags, click the C on the post top-bar, or manually type [ code ][ /code ] around your code.


    ps. Should be NO spaces inside those square brackets....

    Update...

    PropBasic 1.44 is the oldest I could find, and that fails the same way. (OP was using that version too!)

    I tried a simpler code snippet, taken from PropBasic.pdf, and that has the same issue.

    Anyone got an older PropBasic executable to try?

    Thanks Publison.

    Same error with version 1-42.

    Might be something up with the code snippet... Not seeing it right now, but perhaps I'll take a look again later.

    Yes! There's a syntax error; "TASK END" should be "ENDTASK". The COGINIT snippet in the PB manual, p44, is missing the ENDTASK - that's probably the genesis of this simple yet confusing issue.

    Good catch! That was it! All compiles great now.

    @denno code also had END in the wrong place- here's the edited code with both fixes:

    Good call! An extra set of eyes always helps.
  • dennodenno Posts: 223
    Thank you to all, and I did have END in the wrong place and I had TASK END, instead of ENDTASK. One other problem, is I still cannot open ZIP files to get the latest 1.48 PropellerIDE with this Windows 7. Someone sent me the application with a .TXT extention, and said to change it to an .exe file, but that did not work either...any suggestions?
  • VonSzarvasVonSzarvas Posts: 3,450
    Sounds like file extensions are hidden in windows folder settings.

    Make them un-hidden, then renaming files will be easier.

    Google "hide file extensions for known file types"

    Another option is download the .exe direct from Github. I posted the link in your other thread.
