+; This is a basic hello world program for the SplitBit CPU.
+; We'll create a loop that outputs each byte of our string to Output 0, the text console.

+#Program

+Start:
+  LDA         ; Load a byte of the string into A.
+  BRA End     ; If A is zero, branch out of the loop.
+  OUTA 0x00   ; Output the value in A to Port 0, the text console.
+  INCD        ; Increment the Data Pointer to the next byte of the string.
+  BRI Start   ; Branch immediately to the start of the loop.

+End:
+  INIA 0x0A   ; We'll load a linefeed into A and output it to make it look nice.
+  OUTA 0x00   ; Output it to the text console.
