Beginner questions

Begrüßung,
I have start to learn to use Singular software, but I have found
some difficultises. First I would like to ask you if there is a manual
for biginners; I find the present manual very complexe to read (too many "refer to", and we get lost in these references.
I have also used Cocoa, and in few days I have started to write
some procedures (using loops, lists,...), but with singular its rare
that a procedure works (always "error message") even if there is no problem in the program. for example I can write Cocoa procedure for
the tutorial 1.1.13(in the book by Profs. Greuel & Pfister) but can't with Singular. By the way can you please send the solution of this Tutorial and
how to get all the solutions of the other Tutorials. surely I have asked some stupid quetions, sorry. Thank you very much.

An introduction to Singular is the chapter "Getting started" from the manual
(as web page: see
http://www.singular.uni-kl.de/Manual/latest/sing_5.htm
) or the tutorial (which is a collection of some of the examples from the Singular manual, see
http://www.mathematik.uni-kl.de/ftp/pub ... utor.ps.gz

Thank you for the reply,
I have already seen the two websites, but the problem to access
to start Singular (for me) needs a hard work. Here is more details
about my question. To use the present manual we need to know all the invariants in advanced Commutative algebra &algbraic geomery. My knowledge in Com.Alg. is limited(commutative ring theory as in Gilmer Book). My goal is to produce procedures in Singular using just the first level in com.Alg. and elementary Alg.geometry. For example, how to use lists as in Cocoa software. As examples how to return (a list)coefficients of a given polynomial and vice vesa. how to define lists
like >list L=(F| conditions on F). i.e., is it easy to handle lists in Singular as in Cocoa software, ect.
thank you.
