ISBYTE Function (Variant)

Indicates whether a C/AL variant contains a Byte data type variable.

Syntax


Ok := Variant.ISBYTE  

Parameters

Variant
Type: Variant

Property Value/Return Value

Type: Boolean

true if the C/AL variant contains a Byte data type variable; otherwise, false.

Example

The following example determines whether a C/AL variant contains a Byte data type variable. The code initializes the MyByte data type variable with the constant text string A. The MyByte variable is assigned to the variant variable that is named MyVariant. The ISBYTE function determines whether the variant contains a Byte variable and stores the return value in the varResult variable. In this case, the variant contains a Byte variable so Yes is returned and displayed in a message box. This example requires that you create the following variables and text constants in the C/AL Globals window.

Variable name DataType
MyByte Byte
MyVariant Variant
varResult Boolean
Text constant name Enu value
Text000 Does the variant contain a Byte variable? %1.
MyByte := 'A';  
MyVariant := MyByte;  
varResult := MyVariant.ISBYTE;  
MESSAGE(Text000,varResult);
