Terry Holden's article on Wordwise centring (Issue 42) was most interesting, particularly the way Basic can co-exist with Wordwise. However, there is a very simple solution to the problem of underlining centred text. The secret is to enclose everything after the CE command with 'PAD' characters. The formula is:
CE 'PAD' OC27,XX HEADING
OC27,YY 'PAD'
XX and YY being the on and off codes of the printer mode requried. With the NEC-8023 printer, try:
CE: OC27,33,27,88,ENHANCED AND UNDERLINED OC27,34,27,89
