Class: class:word | Namespace: all | Interface Layer: rre

s:put

  Data:  s-
  Addr:  -
  Float: -

Display a string.

Class: class:word | Namespace: global | Interface Layer: all

s:substr

  Data:  sfl-s
  Addr:  -
  Float: -

Class: class:word | Namespace: s | Interface Layer: all

s:tokenize

  Data:  sc-a
  Addr:  -
  Float: -

Takes a string and a character to use as a separator. It splits the string into substrings and returns an array containing pointers to each of them.

Class: class:macro | Namespace: sigil | Interface Layer: all

sigil:'

  Data:  s-s
  Addr:  -
  Float: -

Process token as a string.

Interpret Time:
  Move string into temporary buffer. If `RewriteUnderscores` is `TRUE`, replace all instances of _ with space.

Compile Time:
