     371<p>Many an instruction's modifiers can have parameter that have value 0 or 1. This feature
     372allow to easily parametrize modifiers. The value 1 enables modifier, zero disables it.
     373<code>tfe:0</code> disable TFE modifier, <code>tfe:1</code> enables it. The value of parameter is an expression.
     374The <code>omod</code> modifier with parameter (expression) replaces <code>mul</code> and <code>div</code> modifiers.
     375The <code>format</code> in MTBUF encoding is also parametrizable if data and/or
     376number format expression will be preceded by <code>@</code> character.</p>
