PPWIZARD is a free preprocessor for HTML, REXX, Visual Basic or any text files.
There is no such command although it may at first glance appear so.
The text "#)" is simply the default end of #( block marker if no alternative was specified.
If you find ppwizard telling you that there is no such command then that is perfectly correct. The fault is that the block commands can not appear in a macro.
This "command" used to be called "#OneLineEnd" and you should replace all occurances.
