A suggestion on the Add object, which currently is defined as
Since backwards is not used by any engine, it is safe to make this change. I'd like to add a third element, a replace element. Though, since this should be optional, of course, it would make it difficult for parsers to still look for the backwards keyword, which also is optional. Therefore, I suggest another object Addbackwards, to address this issue.
The new specs would look like this:
Code: Select all
Add=incx incy element1 element2 [backwards]
This was used only in BD2.
if backwards is specified, the algorithm works from bottom up.
The new specs would look like this:
Code: Select all
Add=incx incy search_element add_element [replace_element]
If replace_element is specified, only draw over that element.
incx and incy may be negative numbers.
Addbackwards=incx incy search_element add_element [replace_element]
This is like the regular Add, but works from bottom up.
If replace_element is specified, only draw over that element.
incx and incy may be negative numbers.
