MC-Basic:SYSTEM.DIPSWITCH

SYSTEM.DIPSWITCH reads a value of simulated DIP-Switch from file IO.DAT, from field "DIP". It contains the values of the individual bits in the DIPswitch byte. If SYSTEM.DIPSWITCH is qualified by a bit number, only that input bit is read. SYSTEM.DIPSWITCH.<bit_number> returns the value 1 or 0, depending on the setting of the switch.

File IO.DAT is generated automatically if it does not exist on the flash disk.
Format of IO.DAT
DIP=0xXX
INP=0xXX

Value of simulated DIP-Switch is read via SYSTEM.DIN Value of simulated Inputs is read via SYSTEM.DIN.1 trough SYSTEM.DIN.23

Bit # 6 directs the system not to load the Config.prg file during system startup.
       0= Config.prg and Autoexec.prg are not loaded.
       1 = Config.prg and Autoexec.prg are loaded. Default value should be 1 during normal operation.

Other bits reserved for system use.
