(50g) String inside string manipulation, UserRPL

[DavidM]

It definitely appears that the parser used by STR→ (and by extension, OBJ→) is confused by \" sequence in certain situations. I noticed that "\"" seems to always work, though.

Is there a reason that you have to build the escape sequence in multiple steps? If you keep putting the elements in place on the stack (or better yet, in a list) and then concatenate them all at the end, the final string may be more coherent for the parser. Just a thought.

Otherwise you probably need to start considering alternatives to UserRPL. Either extended functions (as Claudio points out), SYSEVALs or straight SysRPL.

Don't give up!
