Beginners Project: Hello World (using C)

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

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:
