Anyone keen to spend some time helping me with an error?

I'm getting the error mentioned above with Maple 2022 (but can also be reproduced in 2021).

Originally the error comes from within a company library, but I've managed to reproduce it without the library by merging the library in the workbook.

The error arises during a simple addition / subtraction operation, and I have no clue why.

P.S.: I've also filed a request to Maple support on this one.

Just wondering how I do a loop over the contents of the table. I need both the index variable and the stored value associated with it.

This one apparently doesn't work.

F_vRk := table()

table( [ ] )

(1)

F_vRk["a"] := 1

1

(2)

F_vRk["b"] := 2

2

(3)

"for ind, val in F_vRk  do print(ind,val)  end do"

1, F_vRk

(4)

NULL

Maple apparently has managed to destroy the last working piece of code in the Units package in the 2022 release.

This code is working in Maple 2021, but not in 2022 anymore.

alpha := 45*Unit('degree')

45*Units:-Unit(arcdeg)

(2)

NULL

if alpha = 0 then

Error, cannot determine if this expression is true or false: 0 < 1/4*Pi

evalf(sin(alpha))

Is it possible to read and/or convert Mapleflow sheets to Maple?

Any idea why I can't write Excel output to my standard Documents directory?

Writeout to a different directory outside seems to work.

Any specific Windows rights that need to be given to a directory for writeout?
