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
