@rak1507 so i'm curious. about these form and bitmaps using ⎕NEW instead of ⎕WC. are they more efficient or nicer? i do like them because it defines the bitmaps with f← instead of 'f' but is there any other reason?
@BrianBED ⎕NEW is simply a more modern way of doing it, while ⎕WC is from a time when "refs" didn't exist, and GUI objects had to be referred to by character vector name. However, ⎕NEW is very strict on the structure of its argument, while ⎕WC is very lax, so people have kept using ⎕WC for convenience.
now i know that the right part creates a 3 x 3 matrix. but is there something in Dyalog that hierarchically displays how the rest of operators are executed in order? i'm looking for something visually or graphically.
i tried that but i had included the matrix on the right and the numbers on the left but all i got was the answer and i knew i had seen the tree structure before!!
is there a way to see the inputs and outputs to each branch on the tree? that's probably asking a lot!!
the reason i ask is because i assume the matrix is input to the lower + x and what i get from that is a 3x3 matrix of 1's. so are the 3x3 matrix of 1's input to ⊢ . .? i assigned the matrix to A and assigned B to the output of B←+×A.
