Execution of an Expression In A Script

This form of ISSE causes a scripting expression to be executed. The value of the expression is substituted into the Message in place of the ISSE.

The syntax of this form of ISSE is:

{%% expression-indicator : expression-text %%}

Spaces are not significant. There is currently no provision for allowing the sequence “%%}” to appear in the script. (This should not be a problem, since that sequence has no meaning in JavaScript. If it were desired to use that value in a string within the script, something like “’%%’ + ‘}’” could be used within the script.)
