[102] Environment dependence of test casesRequest for clarification2019-08-03 12:56:27
The last two tests seem to depend on a 32-bit cell width.

[110] Etymology of ">IN" nameRequest for clarification2019-08-26 12:25:27
What do >
and IN
mean in the >IN
name?
For comparison, in other names the greater-than sign apparently has the following meaning (when it does not mean greater-than).
In the words like >R
and R>
— >
means data moving direction, and R
means the returns stack.
In the words like >NUMBER
, D>S
or >BODY
— >
means conversion, and a word after the sign is a hint for the target value.

[378] Can This Be Set?Request for clarification2025-06-13 14:21:51
There's no verbiage in the description explaining that the value stored at >IN
can be modified by the user, yet the test cases perform exactly that. Must conforming implementations allow this behavior? Shouldn't there be an explicit note, rather than just an implication, that doing so will cause the very next parsing of a word to start at the new address, and that values stored at >IN
must be char-aligned, and that it's an ambiguous condition to set this value to a region outside of the area returned via SOURCE
?
