Re: Calling a function using a variable name

That would work how I want and may get over the problem I have with 
dynamically including files with XSLT (Which you cannot do). The only 
problem? When I run it I get:

error: program not compiled yet
at: Program.setParameter(Node, Node): index.oml

It seems as though I cannot set a parameter before compiling. Is there 
another thing I have to run before the setParameter function?
  My program looks something like this:

		      <o:set module_to_run="Program($prog_name)"/>
		      <o:do 
select="$module_to_run.setParameter($module/param/@name.string(), 
String($module/param.string()))"/>
		      <o:eval select="$module_to_run.run()"/>
		

Another thing. Can I run the program and pass the output through and 
xsl transform before returning that to the calling program?

Thanks,
Glen
