Title: Problem to update an array
Post by: cameyo on March 16, 2021, 02:50:41 PM

I have the following situation:

Code Select Expand
(setq j (array 256 '(-1)))
(setq str "abc")
(char (str 1))
;-> 98
(integer? (char (str 1)))
;-> true

Now i want to update a value of the array j:

Using the number 98 works:

Code Select Expand
(setf (j 98) 2)
;-> 2

Reference with a variable works too:

Code Select Expand
(setq idx (char (str 1)))
;-> 98
(setf (j idx) 2)
;-> 2

Why the following expressions raise an error?

Code Select Expand
(setf (j (char (str 1))) 2)
;-> ERR: string expected : 2

Using a string as value works:

Code Select Expand
(setf (j (char (str 1))) "2")
;-> "2"

Thanks.

This is fixed here: http://www.newlisp.org/downloads/development/inprogress/

Was a bug in 'char' when used by 'setf'.

Thanks.

When will be released a compiled version?

Best regards,

At the moment I only can compile on FreeBSD 12.2 (Intel CPU), OpenBSD 5.5 (amd64 CPU) and MacOS 11.2.2 (Intel).

No access to Windows or Linux at the moment. What do your need?

Windows and MacOS. But I can wait without any problems.

Thank you.
