.SH DESCRIPTION
.I Size
prints on standard output the number of bytes required
for text, initialized data, and uninitialized data (bss).  It also
prints the sum of these three numbers in decimal and in octal.
For overlaid objects, the sizes of the base and each overlay
segment are also printed.  If no objects are specified, \fBa.out\fP is used.
.PP
Note:  on a separate I/D machine,
the maximum size allowed for nonoverlaid separate I and D objects
(\-i option for \fIld\fP\|(1)) is 65536 bytes for text and 57344 for data
since 8192 bytes of data space are used for the stack.  For standard object
files the limit is 57344.
.SH SEE ALSO
nostk(2), a.out(5)
.SH BUGS
The compilers and loader store size as an unsigned integer and do not check 
to see if the value becomes too large.  Thus the size is truncated for values
above 16 bits and your program may blow up without reasonable error messages.
.SH EXAMPLES
For nonoverlaid objects, the output looks like:
.ta 0.4i 0.8i 1.2i 1.6i 2i 2.4i 2.8i 3.2i 3.6i 4i 4.4i 4.8i 5.2i
