Answer : Truncate text to n character of a string

For someone else further reference: After a lot of headaches
I was able to limit the character of the body field on an announcemnet field in the Schema.xml file by entering the following code in the ViewBody tag:
<ViewBody>

      <HTML><![CDATA[<TR class="]]></HTML>
      <GetVar Name="AlternateStyle" />
      <HTML><![CDATA[" id="borderComponent">]]></HTML>
      <IfEqual>
            <Expr1>
                  <GetVar Name="AlternateStyle" />
            </Expr1>
            <Expr2>ms-alternating</Expr2>
            <Then>
                  <SetVar Scope="Request" Name="AlternateStyle" />
            </Then>
            <Else>
                  <SetVar Scope="Request" Name="AlternateStyle">ms-alternating</SetVar>
            </Else>
      </IfEqual>

      
      <HTML>
            <![CDATA[
                                          <TD width=20% class="ms-vb" style="padding-bottom: 3px"><span class="ms-announcementtitle">
]]>
      </HTML>
      <Field Name="LinkTitleNoMenu" />
      <HTML><![CDATA[</span></TD> <TD width=50% style="padding-left: 2px, padding-right:2px>]]></HTML>

      
      <Limit Len="125" IgnoreTags="TRUE" MoreText="...">
            <Field Name="Body" />
      </Limit>

      
      <HTML><![CDATA[</TD><TD width=10%> ]]></HTML>
      <Field Name="Created_x0020_On" />
      <HTML><![CDATA[</TD><TD width=20%> ]]></HTML>

      
      <Field Name="Author" />
      <HTML><![CDATA[</TD> ]]></HTML>
      <HTML><![CDATA[</TR>]]></HTML>
</ViewBody>
