ENFORC8 environment variable

If ENFORC8 environment variable is set (to any values), the BURP routines dealing with date variables, such as MRBINI, MRBHDR, MRBUPD, MFRLOC, MRFPRM etc., will only accept and return 8 digit date variables in the format YYYYMMDD.

Beginning at January 1 2000, BURP routines will always return 8 digit date variables.
