一个跨越多个版本至今尚健在的BUG:
TD200向生成的数据块，如果再次进入并修改，而对嵌入变量进行移动、删除等 操作，可以触发此BUG。BUG特征：data block编译不能通过。我的做法是，手动修改向导生成的数据。4.x版的似乎与3.x版的稍有不同。
例：
刚生成时：
//Message Enable Bit V34.6
VB6040 '设 总卷数: ' //
VB6054 16#10 //Edit Notification V6054.2; No Acknowledgement;No Password;
VB6055 16#31 //Unsigned Word; 1 Digits to the right of the decimal;
VW6056 16#0000 //Embedded Data Value: Move data for display here.
VB6058 ' 定 导片数: ' //
VB6074 16#10 //Edit Notification V6074.2; No Acknowledgement;No Password;
VB6075 16#30 //Unsigned Word; 0 Digits to the right of the decimal;
VW6076 16#0000 //Embedded Data Value: Move data for display here.
VB6078 ' ' //

改动变量位置后：
//Message Enable Bit V34.6
VB6040 '设 总卷数: 定 导片数: ' //
VB6074 16#10 //Edit Notification V6074.2; No Acknowledgement;No Password;
VB6075 16#30 //Unsigned Word; 0 Digits to the right of the decimal;
VW6076 16#0000 //Embedded Data Value: Move data for display here.
VB6042 16#10 //Edit Notification V6042.2; No Acknowledgement;No Password;
VB6043 16#10 //Signed Word; 0 Digits to the right of the decimal;
VW6044 16#0000 //Embedded Data Value: Move data for display here.
