CAS versus HOME confusion.

[Dominik Holenstein]

Here are my two cents regarding MAKELIST() or makelist().

Used example: makelist(x,x,1,5,1)

Case 1:
HP Prime, CAS mode, x is not defined
1. Choosing MAKELIST from either the Math menu or the Catalogue
2. Entry in the command line: makelist(x,x,1,5,1)
3. Result: []
4. The entry looks now like this: MAKELIST(x,x,1,5,1)
--> expected as x is not defined

Case 2:
Like Case 1 but x has been defined now (x:=0)
1. Choosing MAKELIST from either the Math menu or the Catalogue
2. Entry in the command line: makelist(x,x,1,5,1)
3. Result: [0]
4. The entry looks now like this: MAKELIST(x,x,1,5,1)
--> The HP Prime seems to evaluate something here as x := 0

Case 3:
Like Case 2
1. Choosing MAKELIST from either the Math menu or the Catalogue
2. Entry in the command line: makelist(x->x,1,5,1)
3. Result: [1 2 3 4 5]
4. The entry looks now like this: MAKELIST(x->,x,1,5,1)
--> This method delivers the expected result (Han, many thanks for your hint!).

The HP Prime always capitalises the makelist function. This is not the case with other functions like seq() for example.

Whe I go through the cases 1 - 3 on the HP Virtual Prime (emulator) with the same steps then the makelist() function is not capitalised.

We definitely need a in-depth and detailed HP Prime CAS manual. I will now go through the xCAS reference manual as Miguel (many thanks!) has suggested here.
