syntax error : only (NO)KEEP allowed here
Something other than KEEP or NOKEEP appeared after the closing set of angle brackets (<<) specifying an inline file. Only KEEP, NOKEEP, or a newline character may follow the angle brackets. No spaces, tabs, or other characters may appear.
KEEP preserves the inline file on disk. NOKEEP deletes the file after the NMAKE session. The default is NOKEEP.
