* The recommended method of inputting data into a TEXT field is either by using the Update operation or the File2Blb function. When using this data type in a Direct SQL statement, the maximum blob size will be 64K. To change that size (either increasing or decreasing it) you can use the SQLBLOB = size keyword in the database properties.
Note: When you retrieve data from this field, Magic xpa adds an extra byte to the end of the BLOB. When you use the Blb2File function to save the BLOB to a file, the file size will be one byte larger than the original size.
