The PV SET CELL VARIABLE command links the cell set by column and row to a variable. Any modifications to the cell content will affect the variable and vice-versa.

Example

The following form method displays the current time in cell C3 using the vTime variable. This variable is updated each second, such that the cell acts as a clock:

 C_TIME(vTime) `Variable receiving displayed time

 

 Case of

    :(Form event=On Load)

       If(PV Get cell variable(Area;3;3)="") `Still no variable associated with C3

          PV SET CELL VARIABLE(Area;3;3;"vTime") `Associate the vTime variable

       End if

       SET TIMER(60) `Every second

 

    :(Form event=On Timer)

       vTime:=Current time

 End case
