CRYSTAL REPORT What is x:=x;?

What does this mean in Crystal Report XI?

x:=x;

The whole formula is 

WhilePrintingRecords;
Shared numbervar x;
x:=x;

But it doesn't give any output. Thanks in advance!

Solution

  • The x:=x; section would normally be used to set the value of x eg:

    WhilePrintingRecords;
Shared numbervar x;
x:=10;

    Running this code sets the variable and returns the value set (as long as only a single variable is set), to also return the value of the variable you can add:

    WhilePrintingRecords;
Shared numbervar x;
x:=10;
x

    Or if the variable is set elsewhere, to return the value you can do:

    WhilePrintingRecords;
Shared numbervar x;
x
