        ( "ccc" -- c-addr u )

Skip leading spaces and parse name delimited by space.

c-addr is the address (within the input buffer) and u is the length of the parsed string. If the parse area was empty, the resulting string has a zero length.

See: 3.4.1 Parsing, 6.2.2008 PARSE, A.6.2.2008 PARSE, 6.1.2450 WORD,

        ( x1 x2 x3 -- x3 x1 x2 )

Rotate the top three stack entries.

See: 6.1.2160 ROT

        ( n1|u1 n2|u2 n3|u3 -- flag )

Perform a comparison of a test value n1|u1 with a lower limit n2|u2 and an upper limit n3|u3, returning true if either (n2|u2 <= n3|u3 and (n2|u2 <= n1|u1 and n1|u1 <= n3|u3)) or (n2|u2 > n3|u3 and (n2|u2 <= n1|u1 or n1|u1 <= n3|u3)) is true, returning false otherwise. An ambiguous condition exists if n1|u1, n2|u2, and n3|u3 are not all the same type.

        ( n1|u1 -- n2|u2 )

Add two (2) to n1|u1 giving the sum n2|u2.

See: 6.1.0290 1+

        ( n1|u1 -- n2|u2 )

Subtract two (2) from n1|u1 giving the difference n2|u2.
