This variable determines whether to use the 4GL_2000_CUTOFF variable for dates that do not use a format string and that are 8 digits. 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 variable can also take values of 1 (on, true, yes).
