Thanks, I got this working.
Just a general question. Can you clarify the difference between “tloadnode”,
“tsubscriptnode” and “tcallnode”? I want to make sure I’m using them correctly.
I ask because I’m trying to parse:
wrapper + 1 { wrapper being a record with a default property }
“wrapper” is being parsed as a load node but I want to convert it to
“wrapper.helper” by appending the default property. I found I can make a new
subscript node using the existing load node but is that the preferred method?
p1:=csubscriptnode.create(default_property,p1); { p1 being the load node for
“wrapper” }
Regards,
Ryan Joseph
