Share-Based Payment Arrangement [Text Block] | Note 7 - Stock-based compensation The Company has prior incentive plans under which previously granted awards remain outstanding but under which no new awards may be granted. At April 30, 2023 the Company had reserved a total of 307,446 shares for grants and issuances under these incentive stock plans, which includes a reserve for issuances pursuant to unvested or unexercised prior awards. The Company's prior incentive plans provided for the grant of deferred shares, non-qualified stock options, incentive stock options, restricted shares, restricted stock units, and performance-based restricted stock units intended to qualify under section 422 of the Internal Revenue Code. The prior incentive plans authorized awards to officers, employees, consultants, and independent directors. The Company's 2021 Omnibus Stock Incentive Plan dated May 26, 2021 was approved by the Company's stockholders in May 2021 ("2021 Plan"). The 2021 Plan will expire in May 2024. The 2021 Plan authorizes awards to officers, employees, consultants and independent directors. Grants were made to the Company's employees, officers and independent directors under the 2021 Plan, as described below. Stock-based compensation expense The Company has granted stock-based compensation awards to eligible employees, officers or independent directors. The Company recognized the following stock-based compensation expense for the periods presented:

There was no vesting, expiration or forfeiture of previously unvested stock options during the three months ended April 30, 2023. As of April 30, 2023, there were no remaining unvested stock options outstanding, and therefore no unrecognized compensation expense related to unvested stock options.
