The S-Lang interpreter has very strong support for array-based operations making it ideal for numerical applications. (from [http://www.jedsoft.org/slang/ the official web site]])

Task Output Notes:
For simplicity, many of the S-Lang tasks use the print()
function. This is not part of S-Lang per se, but is normally
included in the "slsh" S-Lang shell. If it is missing, or you're
using some other S-Lang environment, options include a C-like
sprintf() and printf(). Their format and parameters work about
like you'd expect in a C-inspired interpreted language.
sprintf(f, d..) [f=string format, d..=zero or more data items]
returns a string. printf(f, d..) prints to "stdout" and returns
the number of items formatted: remember S-Lang is a "stack
language", so even if you don't care about that number, your code
should "eat" it:
() = printf("S-Lang: %d tasks and counting!\n", 14);
S-Lang is the extension language for the Emacs-like programmer's
editor [http://www.jedsoft.org/jed/ Jed]. There, the output functions
include:
insert(s) write string s into current buffer
vinsert(f,d..) insert(sprintf(f, d..)) ["variable"] equivalent
message(s) write string s into "mini-buffer"
vmessage(f,d..) message(sprintf(f, d..)) equivalent
error(s) like message(), but in error-color, then cancel cmd
verror(f, d..) error(sprintf(f, d..)) equivalent
