Easy language basics beginner Course Series 3

Video Text explanation:

A variable is a sequential bucket with a name. Apply for and name a bucket by defining variables in the source code, and use the bucket by the variable name. A variable is a temporary place for storing data in a program. You can use only one variable or multiple variables in the Code. The variables can store words, values, dates, and attributes.

Easy language variable data type table

Data Type name	Data that can be stored	Initial Value
Byte type	Numeric type, table quantity range: [1, 0,255], occupies 1 byte of storage space.	0
Short integer	Numeric type, table quantity range: [-32768,32767], occupies 2 bytes of storage space.	0
Integer	Numeric type, table quantity range: [-2147483648,2147483648], occupying 4 bytes of storage space.	0
Long Integer type	Numeric type, table quantity range: [-9223372042554775808, 9223372042554775807], occupies 8 bytes of storage space.	0
Decimal type	Numeric type. The value range of a table is ± 3. 4 × 10 ± 38. It occupies 4 bytes of storage space.	0
Double-precision decimal type	Numeric type, the number of tables range: ± 1. 7 × 10 ± 308, occupying 8 bytes of storage space.	0
Logical type	It indicates that data with two values, such as true and false data and men and women, occupies 4 bytes of storage space.	False
Datetime type	Indicates the data of the year, month, day, minute, and second, occupying 8 bytes of storage space.	*

Byte set	It can be used to represent any data, such as video, video, and sound. The meaning of the data represented by it depends on the Data designer.	{}
Subroutine pointer	Indicates the address of the subroutine in the memory. This is a data type specially designed for programming. Occupies 4 bytes of storage space.	0

Easy language variable operation source code Demonstration:

. Version 2

. Supports database spec

. Subroutine _ button 1 _ clicked

. Local variable a, integer type, demonstrate the usage of the Variable

. Local variable B, text type

'Integer variable initial value is 0

A = 1

A = a + 1

A = a + 1

B = "I"

B = B + "love"

B = B + "easy language"

A = a + to INTEGER (B)
