Maybe this is it:

THIS.lnHandle = SQLSTRINGCONNECT(lcConnStrAUSD)

Then you refer to a different property, THIS.lnHandleERCA, here:

lSuccess=SQLEXEC(THIS.lnHandleERCA,"SELECT * FROM myData","cMyData")

Assuming this last line is where the error is occurring, where do you define THIS.lnHandleERCA?
