Problem using Else

[tazntex]

The manual says:

W2 = W0
W0 = W1
W1 = W2
is the same as:
W2 = W0 : W0 = W1 : W1 = W2

So why wont this compile:
IF mydata=%01010110 THEN: HIGH 7:else: low 7: ENDIF:PAUSE 50:GOTO loop
ERROR Line 48: Bad expression. (Test(test mod2).pbp)

I've even tried it as this :
IF mydata=%01010110 THEN HIGH 7:else: low 7: ENDIF:PAUSE 50:GOTO loop

Still no go
I just started to try to use multi-line statements as suggested, sure would look better
