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.
Syntax
System.DipSwitch{.<bit number>}
Sys.DipSwitch{.<bit number>}
?System.DipSwitch{.<bit number>}
?Sys.DipSwitch{.<bit number>}
Availability
Since version 4.11.1
Type
<bit number>: Long
Value: Long
Range
<bit number>: 1 to 8
Value: 0 to 255 (0xFF)
Default
See description.

Examples
MyVar = System.DipSwitch
'MyVar is assigned the value of the input word
MyVar = System.DipSwitch.1
'MyVar is assigned 0 or 1, according to the value of the switch
