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

Create a library for source and program

  • CRTLIB + F4
    • Enter this:

Create a Source Physical File

  • CRTSRCPF + F4, name it SNDBX[1]

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:

  • Close and save with F3
  • Enter 14 to compile
  • Check the outcome with DSPMSG. If you'd rather wait for the compile than queuing it, take a look at Compile Sources Without Queuing.

Run the program

  • CALL SNDBX/HELLO_C:
