Ah. OK, that makes sense. Just a special case of - being a pain. Sorry for false alarm.

It comes down to ambiguous grammar. Quote the variable name and the code works, or include whitespace, because then the ambiguity is gone.

It looks like whitespace is important. This code works as expected:
Code: [Select]
OUTER_SET x = 10
OUTER_SET x -= 2
PRINT "%x%"  // output: 8

Without whitespace around the operator, WeiDU treats "x-" as the variable name that has been assigned the value 2.
Code: [Select]
PRINT "%x-%"  // output: 2

OK, this one surprised me. var1 -= var2 is supposed to abbreviate var1=var1 - var2. Unless I am seriously confused, it doesn't do anything.


Code: [Select]
PRINT "%x%"
Should be 8, actually is 10.
