WRITETD is equivalent to to WRITECD except that, by default, it uses TAB as the delimiter. However, since the introduction of MX_CSVDELIM, to override the default delimiter, the implied distinction between the two WRITExD variations has become misleading, and consequently the use of WRITETD deprecated.
WRITETD will remain supported for compatibility reasons, but the recommended approach is first use MX_CSVDELIM to establish your preferred delimiter—if other than comma—and then stick with WRITECD.
