Okay, this is bizarre. I am testing out some embedded JScript for a related application to what I posted earlier. This one is not happening within the AA, but is nonetheless still inside an AFL.
The following simple code is fine, and does not generate a syntax error:
//Test = 4;
//if ( Test == 4 )
//{
EnableScript( "jscript" );
<%
AB = new ActiveXObject( "Broker.Application" );
AA = AB.Analysis;
%>
//}
However, if I uncomment all the "//" I get a syntax error.
Are we not allowed to call a JScript inside an IF block? If not, why the heck not? And if we are allowed, why would it be generating a syntax error in this simple case?
The error I get is on the "<%" --> probably missing semi colon on previous line.
But the semi colon is clearly there.
Anyone's two cents appreciated.
