Updating Load Modules (1 of 2)

Opposite is an extract from the SYSPRINT of the initial Link Edit of the main program.

The modules RDRRTN and WTRRTN had been compiled and linked prior to the compilation of MAINRTN.

The compile and link of MAINRTN did not require any INCLUDE statements as the library holding RDRRTN and WTRRTN was concatenated onto the SYSLIB DD statement.

NCAL was omitted leaving AUTOCALL as the default, and thus RDRRTN and WTRRTN were successfully incorporated from the SYSLIB library chain.

This output of the initial Link-Edit of MAINRTN
