NAME
       checkobj - check an object file to see whether it can be executed

SYNTAX
       checkobj [ -s ] [ -f ] [ -40 ] [ file ... ]

DESCRIPTION
       Checkobj  attempts to determine whether the named files are valid executable binary files.
       It checks for size restrictions, including those due to the granularity of memory  manage-
       ment  on  the PDP11.  It is especially useful for overlaid object files, where there are a
       number of constraints.  If a file is too large or improperly laid out,  checkobj  attempts
       to point out format changes that would allow the program to run.

OPTIONS
       Several options control the checks:

       -s     Check for the use of separate I/D.  If the file is separate executable, an error is
	      flagged, and an appropriate way to load for a nonseparate machine is  suggested  if
	      possible.

       -f     Check  for  the use of floating point arithmetic without inclusion of the floating-
	      point interpreter.

       -40    Combine the -s and -f options, to check for suitability for an 11/40-class PDP11.

BUGS
       The test for  floating  point  is  simple-minded.   It  is  based  on  the  definition  of
       ``fltused''  by	the C compiler and ``fptrap'' in the floating-point simulator.	This test
       does not work if the object has been stripped.

DIAGNOSTICS
       The exit status is 0 if all named files are runnable with the specified	options,  nonzero
       otherwise.
