Michael,

Also why no Code 3 of 9 Extended?
Code 3 of 9 Extended is included in the set. It is called "Extended code 39" according to ZINT.

I use Code 3 of 9 and don't want the extra "human readable bit" underneath.
We do have on the list to make options for barcodes available but it is not on the short list.

Also the sizing of barcodes is weird. what exactly does the Height parameter measure? as it increases, the codes get smaller?
If the barcode becomes higher the object to place it in must become higher as well else it will be proportionally scaled and thus shows itself less wide. So it is ZINT that takes (or not) the height value and DataFlex Reports tries to fit this in the container you've designed in the report.
