This SIMCVT.C filter should convert Simtel-20's "SIMIBM.IDX" file into a
readable "SIMIBM.LST" that is compatible with the other convert programs,
except for the run-date at the top of the output file.

This program, written in "C" should compile on both 4.3BSD Unix machines,
as well as IBM/pc compatible machines.  It works on both VAXen, and Suns.

To Compile on Unix, type "cc -o simcvt SIMCVT.C" creating simcvt.
To Compile on IBM/pcs, see your C manual that came with the compiler.

To run, type "simcvt < simibm.idx > simibm.lst
