Numeric range operators

HPOM provides six numeric range operators that can be used in pattern matching. The operators are used in this way:

Operator name	Syntax	Example/Explanation
Less than	`<[pattern] -lt n >`	`<[<#>] -lt 5>` matches every number less than 5
Less than or equal to	`<[pattern] -le n >`	`<[<#>] -le 5>` matches 5 and every number less than 5
Greater than	`<[pattern] -gt n >`	`<[<#>] -gt 5>` matches every number greater than 5
Greater than or equal to	`<[pattern] -ge n >`	`<[<#>] -ge 5>` matches 5 and every number greater than 5
Equal to	`<[pattern] -eq n >`	`<[<#>] -eq 5>` matches 5 or 5.0
Not equal to	`<[pattern] -ne n >`	`<[<#>] -ne 5>` matches every number but 5 and 5.0
The operators can also be combined to produce matches according to ranges of numbers:
Matches numbers that belong to the interval, excluding the limits	`< n -lt [pattern] -lt n >`	`<5 -lt [<#>] -lt 10>` matches every number between 5 and 10 ( but not 5 or 10)
Matches numbers that belong to the interval, including the limits	`< n -le [pattern] -le n >`	`<5 -le [<#>] -le 10>` matches every number between 5 and 10 (including 5 and 10)
Matches numbers that do not belong to the interval, excluding the limits	`< n -gt [pattern] -gt n >`	`<10 -gt [<#>] -gt 5>` matches every number between 5 and 10 ( but not 5 or 10)
Matches numbers that do not belong to the interval, including the limits	`< n -ge [pattern] -ge n >`	`<10 -ge [<#>] -ge 5>` matches every number between 5 and 10 (including 5 and 10)

Any time you are working with message text pattern-matching, you can use the left and right mouse buttons to insert expression symbols, as follows:

Mark the text you want to replace with an expression with the left mouse button.
Press the right mouse button for a list of replacement symbol choices.
Select the symbol from the list.

Note that these expressions do nothing unless you replace pattern with a match pattern and n with a number to compare against the value that the match pattern returns.
