Hi,

Why this code doesn't compile (tested version 4.01 and 5.02) ?
Thank you

Hello Benjamin,

1) Still using de-supported FGL version 5.00 ? Please move to latest 5.01!

https://4js.com/download/products/?

2) Your t_donation type is a DYNAMIC ARRAY, which is implicitly passed by reference and does not need the INOUT keyword, reserved for RECORDs

https://4js.com/online_documentation/fjs-fgl-manual-html/#fgl-topics/c_fgl_runtime_stack.html

Try with FGL 5.01 compiler, you will get a better error message:

comment.4gl:14:5:14:24:error:(-8432) An INOUT parameter requires a RECORD type.

Sorry, my fault not have seen that "Declarative dialogs support parameters (SUBDIALOG)" starting at 5.00.03

Thank you
