I've found that most of the time I use a pipe, the in-process pipe works better for me than the normal pipe. Rex, please consider an option (in the .ini file) to specify that |! is implied by | . Perhaps the option Code: pipes=normal pipes=in-process could be used to select which kind of pipe the "|" character will use by default. (The down-side would be that to override it, there'd need to be a different syntax, or the normal pipe usage would need to be preceded by "OPTION //pipes=normal" .) While I'm here talking about pipes, I had trouble finding it in the help file. It could use index entries for | (there is one for ||, but not |) and for |! .
