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 management 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 float-
       ing-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.
