Syntax:

READ variable[,variable...]

Parameter:

variable

A numeric or string variable.

Description:

READ reads as many data values as necessary in turn from data stored by DATA

statement and assigns them, one by one, to each variable in the READ statement.

• If the data type of a read value does not match that of the corresponding variable,

the following operations take place so that no run-time error occurs:

- Assigning a numeric data to a string variable:

The

READ statement converts the numeric data into the string data type and then

assigns it to the string variable.

- Assigning a string data to a numeric variable:

If the string data is valid as numeric data, the

READ statement converts the string

data into the numeric data type and then assigns it to the numeric variable.
