Hi,

the web language requires that subroutines declared as forward cannot have any parameters. Is there a way to remove this restriction?

If you are willing to tie yourself to web2c, then you can use the @define construct in pdftex.defines instead of using a proper forward declaration. I just tried that, it works fine. Otherwise, you will have to change the 'tangle' program, afaik. Best, Taco
