This variable determines whether to use the 4GL_2000_CUTOFF for dates that don't use a format string, and which are 8 digits in length. Setting this variable to "1" causes Acu4GL to apply the 4GL_2000_CUTOFF logic for 8-character long dates. The default value is "0" (off, false, no). This configuration variable can also take values of "1" (on, true, yes).
