I wrote the following command in Text mode:
BTFSC PIR1, TMR1IF
and GCB displayed this properly in Icon mode.
If I write the same line with a comment at the end :
BTFSC PIR1, TMR1IF; Check T1 interrupt bit, if 0 skip next step
the GCB Icon mode converts this to a semi-circle with the word NEXT in it.
Why does it do this?
