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);
