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 SIMCVT.C", and this should create "a.out"
To Compile on IBM/pcs, see your C manual that came with the compiler, and
change the first "c = getchar()" statement depending upon the EOL character.

To run on Unix machines, type    "cat SIMIBM.IDX | a.out > SIMIBM.LST"
To run on IBM/pcs machines, type "type SIMIBM.IDX | simcvt > SIMIBM.LST"
