Record marked as obsolete and not updated for a long time.
The file contains help topics for users, which may be presented as questions and answers or as other information about operating a program.
The .hlm format is obsolete. Its help content was intended for use with the program it relates to, rather than as a general-purpose document.
Use a text editor to inspect any readable content in the .hlm file. A text editor may not display the help as intended if the file uses a program-specific layout.
If a text editor can read the content, use it to copy or save the readable text in another document. This may not preserve its original organization or program-specific behavior.
