>>Please help:
>> I'm trying to create a universal data import table based upon the content of another table I call 'schema'. Schema contains the field names, length, type and start and end points of the fields to be imported from a ASCII file. I'm hung up on creating the new data table using just variables to declare the fields. Here is my latest version of code, and it keeps erroring out on the "Alter Table" command.
