Getting errors not quite sure why this is my first cobol program

Im slowly learning COBOL and am doing some challenges to get better but i am having a weird problem that i cant seem to trace and i wanted to see if anyone else can help

I double and triple checked that what was supposed to be in area A and B where in their proper col numbers

Solution

  • After putting your program into an online compiler (code+results here) two issues were seen:

    • typo: WS-CIRCUMFRENCE -> WS-CIRCUMFENCE
    • missing separator period at the end

    As you seem to not use free format but the column based one I've removed that option (-free from this project, fixed the issues specified above and added the minimal indentation, result: works like a charm.

    I thought about possible issues but the only one I could think of was an additional specification of DECIMAL-POINT IS COMMA - but that raises error: invalid level number '14159', or bad indentation (this would likely be seen); you may want to recheck that you don't do the indentation by TABs (their actual size may differ between what you editor shows and what the compiler uses [most compilers use a size of 8 spaces by default).
