reading variable value from a file

Hello,

I need to read a variable value from script.
Below is the scenario

I am reading a value from an external file say a.txt

a.txt:

Jan
Feb
Mar

I need the corresponding value of the months in in numerics such as Jan -->1,
Feb-->2 etc.

I have this mapping in another file b.txt as

Jan=01
Feb=02
Mar=03

I am reading the text from a.txt, but since i need the numeric values,
I am trying to read the values of these months from b.txt

Plz let me know a possible way out

Thanks a lot!!

SHCOMP(1)						       Korn shell utilities							 SHCOMP(1)

NAME
shcomp - compile a shell script SYNOPSIS
shcomp [ options ] [infile [outfile]] DESCRIPTION
Unless -D is specified, shcomp takes a shell script, infile, and creates a binary format file, outfile, that ksh can read and execute with the same effect as the original script. Since aliases are processed as the script is read, alias definitions whose value requires variable expansion will not work correctly. If -D is specified, all double quoted strings that are preceded by $ are output. These are the messages that need to be translated to locale specific versions for internationalization. If outfile is omitted, then the results will be written to standard output. If infile is also omitted, the shell script will be read from standard input. OPTIONS
[D dictionary] Generate a list of strings that need to be placed in a message catalog for internationalization. [n noexec] Displays warn- ing messages for obsolete or non-conforming constructs. [v verbose] Displays input from infile onto standard error as it reads it. EXIT STATUS
0 Successful completion. >0 An error occurred. SEE ALSO
ksh(1) IMPLEMENTATION
