echo This is an example of how the Mix C compiler can be used to compile
echo a C source file, and link it to make an executable .COM program.
echo The sample C file, called LUMPSUMS.C is first compiled with the
echo command CC LUMPSUMS.

echo Once the file has been compiled it has to be linked with routines
echo from the C libraries to make an executable file. This is done with
echo the LINKER program. The command is just as straightforward - 
echo LINKER LUMPSUMS.
echo     Both these operations, and any debugging of the C program which
echo proves necessary, can be carried out from within the integrated Mix
echo C editor, which along with the trace debugger, will be provided on 
echo next month's SuperDisk.
