The describe statement may return any of the three binary types: IISQ_BYTE_TYPE, IISQ_VBYTE_TYPE or IISQ_LBYTE_TYPE. However, only IISQ_BYTE_TYPE AND IISQ_VBYTE_TYPE can be used when actually sending and retrieving data. The long byte data type must be changed to byte or varbyte if it is less than 32K, or else replaced by a data handler reference type.
