You can use arrays. But the program worked on the PC must send data to Pic by byte variable.

I use a loop in the main program to receive nonstop data.

It usually can process around 19200bps of info with those CASE statements full of code.
I use to receive data also in the CASE statements, because some commands need 1 to 50 bytes of data.

Code:


MAIN:
C = HRSIN 						   
IF C <> $FF THEN

;do something if it is not a start command character ( $FF )

ELSE

	 CMND = HRSIN
	 SELECT CMND
	 
	 CASE X
             do something
	 CASE X+1
             do something
	 CASE X+2
             do something
	 CASE X+3
             do something
	 CASE X+100
             for z = 1 to 50
             i[z] = HRSIN
             next
             do something with that array.

	 ENDSELECT
ENDIF
GOTO MAIN
