CAS versus HOME confusion.

The toolbox produces lowercase makelist() but the display shows MAKELIST() -- which is a different command. This should only happen when the CAS command is the same as the Home command internally (i.e. there is really only one command).

The arguments are essentially the same.

HOME VIEW: MAKELIST(formula, var, start, stop, step)
CAS VIEW: makelist(formula, start, stop, step)

However, the "formula" for the CAS command must be a mathematical function. For example, you can make a function f(x):=x^2. Then do makelist(f,1,2,.1). You can also alternately use the internal format of a function: makelist(x->x^2,1,2,.1).

Please note that a "list" in the CAS is not the same as a "list" in Home.

In general, the toolbox will convert all commands to lowercase if you are in CAS. What you need to watch out for is whether there are two commands of the same name: MAKELIST() for non-CAS, and makelist() for CAS. Another example is STRING() and string(), TYPE() and type().

Wow. CAS is just one chapter long in the HP Prime manual. I downloaded the Xcas reference manual from Parisse's site here. It is a must read to avoid confusion on these "nuances" between CAS and Home.

Thanks Han. I am always amazed of the knowledge that you have on the Prime.

Miguel.
