try Double-Clicking the column name for DataType ...
But that's just gonna sort the list by Data Type, right?
What I meant was ... in a Conventional Programming language, you build your Data Segment any way you want ... and it stays that way forever.
With RSLogix5000, it's always going to put your tags in an alphabetical order, so in order to keep "like" data items together in the list, you have to name them hierarchically so they stay together in a contiguous "chunk" of the list.
