Notes for usage: Mix An intermodulation calculation program.
MIX is written in C, and was compiled using Aztec-C v1.06d on
a Z80 CP/M system with 48k TPA. All steps of the compile
were as follows:
 cc mix.c
 as mix.asm
 ln mix.o -lm -lc

Both input and output data may be redirected from the standard console
device with the angle bracket indicators "<"  for changing input source
and ">" for changing output destination.
To have MIX read its input data from file MIX.DAT and place the output
into MIX.OUT, use this command line:
 MIX <MIX.DAT >MIX.OUT
 
Omitting the output spec will make the console display the results,
and omitting the input spec will put the manually entered data into the
file named when the program was called.

Entering just MIX at the command line will give a sign-on and help message.
The "?" if very brief, just reminding you what MIX needs. Enter the data
the same as shown in MIX.DAT, 1 item per line with the ID first and the data
following a space. You end input and start computation by hitting a
control-z and return.
