I couldn't figure out why there are junk data being output to the stdout:

It's because there is no null-terminator on the parameter data you pass into the C program.

If you run CALL from the command line then string literals are automatically null-terminated but if you run CALL from within a program you have to ensure either:
1) a null-terminator is present
2) write you C program to handle character data without a null- terminator.

The ILE C/C++ Programmer's Guide explains this behaviour.
