DATA, READ, RESTORE
Updated: Nov 14, 2005

DATA literal[,literal[,etc]]

  Entries in DATA statements are treated literally.  That is, "JOHN" is
  different than JOHN.
  Suggestion: The first item in a DATA statement might be a count of the
  remaining items.  This count may be READ and used to set the number of
  additional READs.

  Obviously, comments in a DATA statement will be treated as data.

  DEFINT i, j: DEFSTR a$, b$
  DATA 3,100,HotBabe,Maj. Hog
  READ i, j, a$, b$  'i=3; j=100; a$="HotBabe"; b$="Maj. Hog"

READ MyVar

  Data type is determined only by the variable type used in the READ statement.
  As a precaution to prevent errors, READ should return NULL for an attempt to
  READ past the end of DATA statements.  "MyVar" above may be an array element,
  e.g., READ A(i,j)

RESTORE [label]

  The optional [label] must appear in source code before a RESTORE statement
  using the label -- for this one-pass compiler.  You might consider putting
  DATA statements with labels among them near the beginning of source code --
  perhaps in an $INCLUDE file.  If RESTORE to a specific line label is not
  used, then DATA statements can be anywhere in source code.

hotdata.bas and hotdata1.bas in HotTrial provide working code examples.
