I do not understand the fields of pushpins?

using MP2002 and vb6

I think this is how it works but can't figure out the code

Some how I set the field names when creating the datasets

Set objDataSet = objApp.OpenMap(objApp.Path & "\Samples\Sales.ptm").DataSets("SampleData")

I want to be able to enter the field names from my program not data file

Then I give each pushpin a value for the field as they are added ????


Problem is I import the data as arrays at the beginning of my program
(TRKUnit(1000,9) = unit,lat,long,status etc..) and am changing field values
like the lat , long and status regularly

can I change the field values of the pushpins regularly
??? objPushpin.field(2) = "some text"

I tried searching the discussions for "pushpin fields" but ????
