In this blog post, I will take you through how the basic structure of the CL program will be.
In General,
  • CL Code is case insensitive.
  • Source code usually starts from column 14 with an indentation for readability.

  • Every programing language has some notation for adding comments which are used for future reference. Likewise in CL, Comments are marked by /* at the beginning and */ at the end.

  • If your message exceeds the line limit, we can use + for continuation, + can be entered at any column.

Now we will see how the structure will be
The basic structure of the CL program is 
  • PGM Command
  • Declare Commands
    • Variable declaration
    • File declaration
  • Global Error handling
  • CL Processing Commands
  • Logical Control Commands
  • Built-in functions
  • Program and Procedure Control Commands
  • ENDPGM Command
