We agree with Shawn. It is a great idea, but we think that it can cost
a lot of time for implementation.
Reasons:

• how is it implemented by REXX? We think that the file will be read
  by an internal REXX command and it will read from memory or possible
  an unknown temporary file.
  Reading such information from memory needs special functions. Reading
  from a file is must easier.
  
• how much kixpipe handle incorrect lines. f.e. you only get
  lines with a LF instead of CR+LF.
