As noted with the configuration variable immediately above (A4GL-MIN-DATE), invalid dates could be incorrectly written to the database. Invalid dates are written as NULL, but if the date is in the key, problems can occur. To avoid invalid date problems in this instance, use the A4GL-MIN-DATE configuration variable to set the low-value date.
The format is A4GL-MIN-DATE = YYYYMMDD.
The default date for A4GL-MIN-DATE is 19000101 (January 1, 1900).
Presently, this variable is only used with the Acu4GL for ODBC software.
