Error checking occurs as data is read in and during the internal data preparation. Checks for acceptable characters based on data field type (Alphanumeric, integer, logical, and floating point); numeric data within acceptable range; and inter-field relationships on a single input record are made as data is read. Checks for inter-record relationships and identifier comparisons between data section header groups are performed after all data is read. Appropriate error messages are placed in the error file when errors are encountered.
