Read-line for .lsp

[Anonymous]

Is there a way to "read-line" on a Lisp file? I'm looking to be able to compare a number between 2 different files, and my attempts thus far have bore no fruit.  I'd appreciate any advice on the subject.

Comparing text files?  Look into a diff generator such as WinDiff or TortoiseMerge.

Hi,

You can read a .lsp fine as any other text file.

(setq file (open (findfile "edge.lsp") "r"))
(while (setq line (read-line file))
  (setq lst (cons line lst))
)
(close file)
(reverse lst)

Tortoise looks like it's exactly what I looking for, Thanks.
