VALIDATA(1)                        |STAT                      March 5, 1985

NAME
     validata - validate and report columnar file consistency

SYNOPSIS
     validata

DESCRIPTION
     validata reads a file from the standard input and for each column in
     its input, reports statistics about the data type of fields (whether a
     column contains alphanumeric strings, integers, real numbers, or
     something else).  validata also reports the maximum and minimum values
     of the columns; validata is useful to check data files for consistency
     before input to some data analysis program because it detects missing
     columns or columns of the wrong type, such as non-numeric input.
