| defines a relation between an atom and a list of the codes of one-character atoms.
atom_codes(+Atom, -List)
atom_codes(-Atom, +List)
If Atom is an atom then atom_codes/2 explodes Atom
into a list of character codes.
If Atom is a variable then List must be a list of
character codes. atom_codes/2 converts the character codes to
characters and concatenates these characters to the atom Atom.
Arguments
Atom atom
List list of charactercodes (between 0'\u0000 and 0'\uffff)
Examples
| atom_codes(abcde, L). |
Succeeds with substitution L <- [97, 98, 99, 100, 101]. |
| atom_codes(A, [108,105,116,117]). |
Succeeds with substitution A <- list. |
| atom_codes(list, [108,I,116,T]). |
Succeeds with substitution I <- 105, T<- 117. |
