Controls the output format of the mhl command.
The /etc/mh/mhl.format file controls the output format of the mhl command when the mhl command functions as the message listing program. The /etc/mh/mhl.format file is the default attributes file. The mhl.digest, mhl.forward, and mhl.reply files must be specified before use.
Each line of the mhl.format file must have one of the following forms:
The following table lists the mhl.format file variables and parameters.
| File Variables for the mhl.format File | ||

| OverflowText | string | Outputs the String parameter at the beginning of each overflow line. |
| OverflowOffset | integer | Indents overflow lines the specified number of columns. |
| CompWidth | integer | Indents component text the specified number of columns after the first line of output. |
| Uppercase | flag | Outputs text of the Component parameter in all uppercase characters. |
| NoUppercase | flag | Outputs text of the Component parameter in the case entered. |
| ClearScreen | flag/G | Clears the screen before each page. |
| NoClearScreen | flag/G | Does not clear the screen before each page. |

| NoBell | flag/G | Does not produce an audible indicator at the end of each page. |
| Component | string/L | Uses the String parameter as the name for the specified the Component parameter instead of the string Component. |

| LeftAdjust | flag | Strips off the leading white space characters from each line of text. |

Variables that have integer or string values as parameters must be followed by an = (equal sign) and the integer or string value (for example, overflowoffset=5 ). String values must also be enclosed in double quotation marks (for example, overflowtext="***" ). A parameter specified with the /G suffix has global scope. A parameter specified with the /L suffix has local scope.
The following is an example of a line that could be displayed in the mhl.format file:
width=80,length=40,clearscreen,overflowtext="***".,overflowoffset=5
This format line defines the screen size to be 80 columns by 40 rows, and specifies the screen should be cleared before each page (clearscreen ). The overflow text should be flagged with the *** string, and the overflow indentation should be 5 columns.
