• Main-Pgm: The name of the member that contains the main program, that is usually the

name of the load module. In our example "A“.

• Main-Lib: The name of the Library, where "A" was found. In our example SOURCE.LIB.

• INCLUDE-Member: The name of the member with the INCLUDE statement. That is not

always identical to the main program, e.g. the INCLUDE statement is nested in another

INCLUDE member. In our example “A” for “B” and “B” for “C”.

• Found: Shows if the INCLUDE member was found in one of the libraries specified during

the XINFO installation. In our example “Y(es)” for “B” and “N(o)” for “C”

• Line: The line number of the INCLUDE statements. In our example “25” for “B” and “50” for

“C”

• Source lib: The library where the INCLUDE member was found. In our example

“SOURCE.LIB” for “B” and “INCLUDE.LIB” for “C”
