Since Heiko is fairly familiar with C, here's his approach for a simple "Hello World!" in C.

Create a Source Physical File

  • CRTSRCPF + F4, name it SNDBX

Create the C source code

  • To create the source code as member of the SPF: WRKMBRPDM + F6, enter name (hello_c) and type (C):

  • Enter this in SEU:
