READ

Syntax

READ {constant,} variable_list

variable_list = variable | array_element | string_element {, variable_list }

Description

Reads data stored by the BASIC application with the DATA command.

The elements of the variable_list must be integer variables, elements of a string, or elements of arrays. Each element read, will be filled from a 32bit value in the 4K space used to store the DATA statements. All the DATA statements in the program behave as a single list.

After the last element of a DATA is read, the first element of the following DATA will be read.

The RESTORE statement resets the next-element pointer to the start of the DATA. This allows the user to alter the order in which the DATA are READ.

If the READ is followed by a constant, then the element will be filled from the nth DATA element where n = constant.

Example

' Create an array of 5 integers.
DIM h(4)

' Set up to loop 5 times (for 5 numbers... check the data)
FOR read_data = 0 TO 4

' Read in an integer.
READ h(read_data)

' Display it.
PRINT "Number"; read_data;" = "; h(read_data)

NEXT

END

' Block of data.

DATA 3, 234, 4354, 23433, 87643

Differences from other BASICs

Most classic BASICs contain this construct
Does not exist in Visual BASIC
PBASIC allows modifiers for size. In PBASIC the first element always sets the offset into the data array. This is the case in ARMbasic only if the first element is a constant.
