R Singh, Looks like we have a winner. I am not well versed on AWK, only grep and sed. I will study this and see if I can understand it. Thanks for the help!
How will you change the 5th column in the data file with the value in the second column in the error_correction.txt file.
You have to match an extra variable, column 3 of the error_correction file with column 6 of the data.txt file.

isalpha
ISALPHA(3) BSD Library Functions Manual ISALPHA(3)NAME
isalpha -- alphabetic character test
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <ctype.h>
int
isalpha(int c);
int
isalpha_l(int c, locale_t loc);
DESCRIPTION
The isalpha() function tests for any character for which isupper(3) or islower(3) is true. The value of the argument must be representable
as an unsigned char or the value of EOF.
In the ASCII character set, this includes the following characters (with their numeric values shown in octal):
101 ``A'' 102 ``B'' 103 ``C'' 104 ``D'' 105 ``E''
106 ``F'' 107 ``G'' 110 ``H'' 111 ``I'' 112 ``J''
113 ``K'' 114 ``L'' 115 ``M'' 116 ``N'' 117 ``O''
120 ``P'' 121 ``Q'' 122 ``R'' 123 ``S'' 124 ``T''
125 ``U'' 126 ``V'' 127 ``W'' 130 ``X'' 131 ``Y''
132 ``Z'' 141 ``a'' 142 ``b'' 143 ``c'' 144 ``d''
145 ``e'' 146 ``f'' 147 ``g'' 150 ``h'' 151 ``i''
152 ``j'' 153 ``k'' 154 ``l'' 155 ``m'' 156 ``n''
157 ``o'' 160 ``p'' 161 ``q'' 162 ``r'' 163 ``s''
164 ``t'' 165 ``u'' 166 ``v'' 167 ``w'' 170 ``x''
171 ``y'' 172 ``z''
The isalpha_l() function takes an explicit locale argument, whereas the isalpha() function uses the current global or per-thread locale.
RETURN VALUES
The isalpha() function returns zero if the character tests false and returns non-zero if the character tests true.
COMPATIBILITY
The 4.4BSD extension of accepting arguments outside of the range of the unsigned char type in locales with large character sets is considered
obsolete and may not be supported in future releases. The iswalpha() function should be used instead.
SEE ALSO ctype(3), islower(3), isupper(3), iswalpha(3), xlocale(3), ascii(7)STANDARDS
The isalpha() function conforms to ISO/IEC 9899:1990 (``ISO C90''). The isalpha_l() function conforms to IEEE Std 1003.1-2008 (``POSIX.1'').
