DOSWITCH is like an switch to select an specific pre-defined line on the code

Code:

DOSWITCH 3

  SYSMESSAGE Message 0

  SYSMESSAGE Message 1

  SYSMESSAGE Message 2

  SYSMESSAGE Message 3

  SYSMESSAGE Message 4

ENDDO

this will make the code return "SYSMESSAGE Message 3"

of course it doesn't make sense use an fixed switch like this example, because if we always want the line 3, it makes more sense use directly "SYSMESSAGE Message 3" instead an useless DOSWITCH with many results but always returning the same fixed result 3

so DOSWITCH is usefull on situations where you already have some pre-defined lines and want trigger the correct line based on some other value, like this:

Code:

DOSWITCH <DIR> //this return an 0-7 value based on the direction your char is facing

  SYSMESSAGE You are facing N

  SYSMESSAGE You are facing NE

  SYSMESSAGE You are facing E

  SYSMESSAGE You are facing SE

  SYSMESSAGE You are facing S

  SYSMESSAGE You are facing SW

  SYSMESSAGE You are facing W

  SYSMESSAGE You are facing NW

ENDDO

in other words, DOSWITCH does the same thing as this code below but using an clean/optimized code

Code:

IF (<DIR>==0)

  SYSMESSAGE You are facing N

ELIF (<DIR>==1)

  SYSMESSAGE You are facing NE

ELIF (<DIR>==2)

  SYSMESSAGE You are facing E

ELIF (<DIR>==3)

  SYSMESSAGE You are facing SE

ELIF (<DIR>==4)

  SYSMESSAGE You are facing S

ELIF (<DIR>==5)

  SYSMESSAGE You are facing SW

ELIF (<DIR>==6)

  SYSMESSAGE You are facing W

ELIF (<DIR>==7)

  SYSMESSAGE You are facing NW

ENDIF
