Re: V8 javascript in OpenCOBOL

Ok, three tries.

OCOBOL >>SOURCE FORMAT IS FIXED

       data division.
       77 result     usage binary-long.
       01 v8-value   pic x(32767).

      *> -*********-*********-*********-*********-*********-*********-**
       procedure division.
       display "Calling CBL_OC_V8JAVASCRIPT" end-display

       call "CBL_OC_V8JAVASCRIPT"
           using
               "'Hello' + ', world'"
               v8-value
               by value function length(v8-value)
           returning result
           on exception
               display "v8 linkage problem, result garbage" end-display
               continue
       end-call
       
       display "V8 gives :" function trim(v8-value) ":" end-display

       goback.
       end program ocv8.

Forgot the C string null on the CALL literal. I've updated the original post. The listing above is the unsafe version for context. Don't cut nor paste this one.

Plus: This discussion on LinkedIn has led to the idea of a new project to attempt to embed Node.js into OpenCOBOL. I'm going to try a CALL interface first.

Cheers,
Brian
