Where SomeDateField = ?dDateParm also returns logical which is what you are using now, correct? There is no difference in that than in using the BETWEEN() function. You are telling your query to return all records that have a date inclusively between 2 date values. The following are identical:

where SomeDateField >= ?dBgnDateParm and SomeDateField <= ?dEndDateParm

where between(SomeDateField, ?dBgnDateParm, ?dEndDateParm)

If you want only those records for a single Date value, you make dBgnDateField the same date as dEndDateParm.
