s5delphi.zip    S5 like plc simulation with source code

***This is a new version of my previously uploaded file s5delph2.zip***!

s5 is simulation program for plc like device, that are programmable
with a logic instruction language. The instruction language consist
of logic operation (and, or and-not, or-not) and operands like inputs,
outputs, markers, timers, counters and date and time functions. Some
outputs can be written to one of the parallel ports, to connect any
real hardware, some would like to use.
