Re: implementation of 2-dimensional array in bash - kind request
Thanks. You are right as always. I am trying to master dialog and for my tiny application bash + 2D arrays + dialog should suffice.

Re: implementation of 2-dimensional array in bash - kind request
C is a good solution. So is Perl, which comes on OS 2008. So is Python. Perl lets you construct nested lists, which gives you the equivalent in capability to multi-dimensional arrays. Python gives similar constructs. There is no reason IMHO to be writing shell scripts of any kind on a system where Perl and Python are available. Shell programming is just weak for many reasons including lack of data structure capabilities and should be avoided whenever possible. I say this as someone who has accumulated years of shell programming experience in a professional software shop as well as other languages. The strongest of the shell programming languages, namely bash and ksh, have this problem. Perl and Python are practical for exactly the reason that they are good replacements for these shell languages. -Will Kees Jongenburger wrote: Hello Darius, On Sat, Jul 5, 2008 at 7:54 PM, Darius Jack [EMAIL PROTECTED] wrote: and have 2D array inmterpreted as one row. so calculating array2D ( ) i-th j-th element as i + (j-1) x row length I agree with Igor what using bash or even better a POSIX shell would be a little insane.

Perl is my favorite language, but the perl install on the tablets is missing a lot of the standard modules. For example, 'perl -e use English;' gives an error. python seems to be a more complete install and even includes gtk, so it's arguably the best choice of scripting language for the platform given what's preinstalled and in extras.
