I can't completely answer your question but hopefully I can point you
in the right direction.  The bytes that hold the module flags are found
at offset 0Ch from the start of the New EXE header.  The location of the
New EXE header is a long value found at offset 3Ch from the start of the
file.  The module flags are contained in the two bytes at 0Ch past the
value found at 3Ch.  The value found at offset 8h from the start of the
New EXE header is the files CRC value.  When you change the module flags
this value will also change.  My linker (IBM v5.05) doesn't want to
accept LONGNAMES or NEWFILES (which is what my documentation says to use)
so I can't determine which bit in the module flags gets set when that
option is selected.  What version of the IBM linker are you using?
