Table 3–12: Embedded SpeedScript expression escapes
Start tag	End tag	Comments
‘	‘	The back tic ( `‘` ) is acceptable to most authoring tools. This escape can be difficult to spot in code, depending on the font.
{=	=}	This escape is easier to spot than the back tic and is also acceptable to most authoring tools.
<%=	%>	These are Microsoft Active Server Pages (ASP) command tags. These tags might cause problems for some authoring tools because they use the angle brackets (`<` `>`).
<!--WSE	-->	This escape is a WebSpeed-defined HTML comment and is therefore supported by virtually all authoring tools. You might be able to use this escape to place embedded SpeedScript where some authoring tools consider other tags illegal, such as before `<HTML>` or after `</HTML>`.

An expression escape can enclose any sequence of valid SpeedScript expressions with a character output format, including variables, database fields, functions, and literal character strings. You can place expression escapes either alone or as part of an HTML string.

In escript3.htm, each SpeedScript expression is a database field inserted in an HTML table cell. Note how the statement escapes are distributed among the table tags to return a new customer record for each table row:
