[34] BL rationale is wrongProposal2017-10-25 11:35:46
Both Forth-2012 and Forth-94 specify ASCII as character encoding, so we know that the value of BL is #32 (or $20). The rationale claims that BL is the only way to get this value, but it is wrong.

Indeed, so we could move BL to core ext to make it optional.
There's no need for a size constrained system to contain a word that's trivially replaced by a literal with known value.

Yet another way to find the system value of "space" is : _BL ( -- c ) S" " DROP C@ ;

Due to a bug in the web-site engine, now it renders two spaces as one in an inline code fragment:
: _BL ( -- c ) S" " DROP C@ ;
\ It shows a string having length 0
S" "
\ instead of a string having length 1
S" "
(it works in code blocks, but doesn't work in inline code fragments)
