See the following for details regarding to statement content.
DATA Statement
Function READ statement sets replacement data in each variable.
Format DATA constant [, constant, …]
Constant: Numeric
Explanation DATA statement can be placed anywhere in the program or even dispersed.
Space is ignored for numeric variables in the READ statement.
The RESTORE statement enables the DATA statement read by the READ
statement to be set by line unit
Up to 1024 constants can be used as a parameter after DATA.
DEFINT/DEFSNG/DEFDBL Statement
Function Declares type of variable.
Format (1) DEFINT variable name [, variable name…]
(2) DEFSNG variable name [, variable name…]
(3) DEFDBL variable name [, variable name…]
Explanation Declares type of variable. All variables specifi ed with initial characters of variables
become the specifi ed type.
DEFINT declares variable as an integer.
DEFSNG declares variable as a single precision real number type.
DEFDBL declares variable as a double precision real number type.
The specifi ed initial character of the variable is one uppercase alphabetic
character. For any of the formats (1) to (3) listed above, it is necessary to make the
declaration before the variable name is described in the program block. Complex
sentences cannot be described.
The maximum of 16 variables can be defi ned at one time.
Regarding to the defi nition of variables, see Section 1.5 Variables.
DIM Statement
Function Declares array variables.
Format DIM_ARRAYNAME_AS_TYPE
Array name: Name of array
Type: INTEGER, REAL, DOUBLE
Explanation Declares as either one-dimensional array or two-dimensional array.
Regarding to the defi nitions of array variables, see Array Variables in Section 1.5
Variables.
