Earnings Per Share [Text Block] | NOTE 6 – NET LOSS PER COMMON SHARE Basic net loss per common share is computed by dividing the net loss by the weighted-average common shares outstanding. Options, deferred stock units, convertible debt, convertible preferred shares and warrants were not considered in the computation of net loss per share because their inclusion would have been antidilutive. Had these instruments been included, the fully diluted weighted average shares outstanding would have increased by approximately 5,029,000 and 1,533,000 for the three months ended June 30, 2023, and 2022, respectively; and 5,029,000 and 1,533,000 for the six months ended June 30, 2023 and 2022, respectively.
