1 DATA
 The DATA statement creates a data block for the READ statement.

 Example

 DATA 35,32.3,PRODUCTION SEQUENCE,"SYSTEM","1,2"

1 Data_types
 All data in a BASIC program have a specific data type that determines  how
 many bits of storage should be considered as a unit and how the unit is to
 be interpreted and manipulated.

 BASIC  recognizes  five  primary  data  types:   integer,  floating-point,
 character string, packed decimal, and RFA.  These data types correspond to
 the INTEGER, REAL,  STRING,  DECIMAL(d,s),  and  RFA  keywords.   You  can
 specify  the default type and size of numeric data with qualifier keywords
 or the OPTION statement.  You can also explicitly declare the  data  types
 of variables and constants with declarative statements.

2 INTEGER
 Integer data are stored as binary  values  in  a  byte,  a  word,  or  a
 longword.  These values correspond to the BYTE, WORD, and LONG data type
 keywords.

 Keyword             Range

 BYTE (8-bit)        -128 to 127
 WORD (16-bit)       -32768 to 32767
 LONG (32-bit)       -2147483648 to 2147483647

 When used in  declarative  statements,  the  INTEGER  keyword  specifies
 integer data of the default integer size.

2 REAL
 Floating-point values are stored using a signed exponent  and  a  binary
 fraction.   BASIC  allows  four floating-point formats:  single, double,
 gfloat, and hfloat.  These formats correspond  to  the  SINGLE,  DOUBLE,
 GFLOAT, and HFLOAT keywords.

 Keyword             Range                                  Precision

 SINGLE (32-bit)    .29 * 10^-38 to 1.7 * 10^38              6 digits
 DOUBLE (64-bit)    .29 * 10^-38 to 1.7 * 10^38             16 digits
 GFLOAT (64-bit)    .56 * 10^-308 to .90 * 10^308           15 digits
 HFLOAT (128-bit)   .84 * 10^-4932 to .59 * 10^4932         33 digits

 In declarative statements, the  REAL  keyword  specifies  floating-point
 data of the default floating-point size.

2 DECIMAL
 The DECIMAL(d,s) data type keyword specifies  packed  decimal  data.   A
 packed  decimal  value  has  a  specified  number  of  digits  (d) and a
 specified decimal point position (s).

2 RFA
 The RFA data type keyword specifies a Record File Address (RFA).  An RFA
 uniquely  specifies a record in a file.  You can access RMS files of any
 organization by Record File Address (RFA).  The RFA data type is  unique
 and can be used only for:

  o  RFA  operations  (with  the  GETRFA  function  and  GET   and   FIND
     statements)
  o  Assignments to other variables of the RFA data type
  o  Comparisons with other variables of the  RFA  data  type  using  the
     equal to (=) or not equal to (<>) relational operators
  o  Formal and actual parameters
  o  DEF and function results

 The RFA data type requires six bytes of storage.

2 STRING
 The STRING data type keyword  specifies  character  string  data.   Each
 character is stored in one byte.
