The first four lines of a function in stored procs are as follows:
function WhatEver
parameters TableField
FName = proper(substr(TableField, at(".", OldF) + 1))
FText = dbgetprop(TableField, "Field", "Caption")

I know that the TableField parameter is TableName.FieldName because line 3 returns the fieldname.
However, line 4 produces an error (Invalid function argument type)
TableName.Fieldname is an integer field but, I'm not sending the contents, just the name.
It appears that dbgetprop is evaluating the contents.

How can I get the desired "Caption"?
