What am I doing wrong here? I saved this very short program as 'test.lsp':
(set 'infile (open (main-args 2) "r"))
(print (read-line infile) "n")
(close infile)
It is in a directory with this very short file called 'test.txt':
a_label:
If I run this on the Windows console command line:
newlisp test.lsp test.txt
I get:
a_label:
ERR: symbol expected : "a_label:"
and am back in the command console.
If I change test.txt to:
a_label
It opens the file, prints 'a_label', and leaves me in newlisp, where I should be.
What is that colon doing?

(Oops, edited, because in the original posting I left out the 'a_label:' which atually gets printed)
Me again already.
If test.lsp is reduced to:
(set 'infile (open (main-args 2) "r"))
(close infile)
Then I still get the result:
ERR: symbol expected : "a_label:"
And back into the command line.
Seems like newLISP is reading the contents of the file without being asked. :(
I know it must be me, it always is. I've missed something.

this is what happens after executing on the command-line
newlisp test.lsp test.txt
newLISP loads test.lsp and executes it, which loads test.txt. Because test.lsp does not exit, newLISP tries to load text.txt as a program and tries to evaluate the string "a_label:". Because the ":" is syntax in newLISP awaiting a symbol after it.
Put and (exit) statement at the end of test.lsp and everything will be fine ;-)
Thanks Lutz, much obliged. I knew it was me (so I got that bit right).
A lesson soundly learned.
