Copybook

Copybook is a python module for parsing VSAM copybooks.

Features

• Supports all numeric PIC variations including:
  • integers
  • floats described with dot notation
  • floats described with V notation
  • leading SIGNED
  • trailing SIGNED
• Character PIC notations
• Groups
• OCCURS clauses
• REDEFINES clauses

In addition, it provides indexes of column locations to help with parsing fixed width files based on positions within each line

Installation

pip install copybook

Usage

Copybook provides two methods for parsing copybooks: parse_file and parse_string. The result is a FieldGroup object that represents the root of the copybook tree.

Examples:

import copybook
text = """
       01  WORK-BOOK.                                  
        10  TAX-RATE        PIC S9(13)V9(2)                
                    SIGN LEADING SEPARATE.                                     
"""
root = copybook.parse_string(text)
