That it compiled without errors only means your program is correct grammatically, the same way "my hovercraft is full of eels" will pass a grammar check but not help Belgians communicate with foreigners. Your program does not do what you think it does.
'a' and 'b' are the ASCII integers 91 and 92, respectively. They are not the arrays a and b and cannot be used to retrieve those variables.
How about this?

Hi experts,
I am totally stuck with this.
I run a looping "for" command for multiple directories, manually, I have done this :

ocamlyacc
OCAMLYACC(1) General Commands Manual OCAMLYACC(1)NAME
ocamlyacc - The Objective Caml parser generator
SYNOPSIS
ocamlyacc [ -bprefix ] [ -q ] [ -v ] [ -version ] [ -vnum ] filename.mly
DESCRIPTION
The ocamlyacc(1) command produces a parser from a LALR(1) context-free grammar specification with attached semantic actions, in the style
of yacc(1). Assuming the input file is grammar.mly, running ocamlyacc produces Caml code for a parser in the file grammar.ml, and its
interface in file grammar.mli.
The generated module defines one parsing function per entry point in the grammar. These functions have the same names as the entry points.
Parsing functions take as arguments a lexical analyzer (a function from lexer buffers to tokens) and a lexer buffer, and return the seman-
tic attribute of the corresponding entry point. Lexical analyzer functions are usually generated from a lexer specification by the ocam-
llex(1) program. Lexer buffers are an abstract data type implemented in the standard library module Lexing. Tokens are values from the con-
crete type token, defined in the interface file grammar.mli produced by ocamlyacc(1).
OPTIONS
The ocamlyacc(1) command recognizes the following options:
-bprefix
Name the output files prefix.ml, prefix.mli, prefix.output, instead of the default naming convention.
-q This option has no effect.
-v Generate a description of the parsing tables and a report on conflicts resulting from ambiguities in the grammar. The description is
put in file grammar.output.
-version
Print version string and exit.
-vnum Print short version number and exit.
- Read the grammar specification from standard input. The default output file names are stdin.ml and stdin.mli.
-- file
Process file as the grammar specification, even if its name starts with a dash (-) character. This option must be the last on the
command line.
