I am working on 4gl language but a new bie. In a file custom.4gl a function cleanup() is called, but I didn't find the function definition. I am trying to find that.

I got a file named 'tags' with following line of code in which a hint for cleanup is there. But I didn't understand what this meant. Can anyone help me to find the function definition.

I folder searched with my code editor but there was no way.

```
cleanup custom.4gl  /^function cleanup(
cn_error_handler    cnerhand.4gl    /^function cn_error_handler(
default_code    custom.4gl  /^function default_code(
get_file    custom.4gl  /^function get_file(
get_params  custom.4gl  /^function get_params(
get_prompts custom.4gl  /^function get_prompts(
logo    main.4gl    /^function logo(

```
