It does but not as easily as in DOS!

It was a long time since I did this but if I remember correctly you need 
to first create a Crosstab in a a form and then you can use the 
AcctionDataCommand DataSaveCrosstab for the uibojcet which will create a 
table CROSSTAB.DB in PRIV.

I used something like this:

Open a hidden form with the crosstab

Issue uiCrossTab.action(DataSaveCrosstab)

Close the hidden form

Work with the Crosstab table.

There are probably a better way but that was how I solved it a long time 
ago...
