Description

When peUpdateMode is umPromptCustom or umPromptNonInvoking, you can use psSeedValue to define a seed value. This is used along with piUpdateColumn to seed the table buffer and find a record. See SeedData for a complete description of this process.

If peUpdateMode is umPromptCustom, psSeedValue will probably be set in the invoking object's Prompt_Callback event. 

Procedure Prompt_Callback Integer hPrompt
    String sValue

    Set peUpdateMode of hPrompt to umPromptCustom
    Set piUpdateColumn of hPrompt to 1 // on name column
    Set phmPromptUpdateCallback of hPrompt to (RefProc(PromptUpdate))
    Get Value of oMyStartForm to sValue
    Set psSeedValue of hPrompt to sValue
End_Procedure

If peUpdateMode is umPromptNonInvoking, psSeedValue will probably be set inside of a custom method within the prompt object's modal panel object.

// This would be added to the prompt list's panel object.
Function GetSelectedName String sSeed String ByRef sName Returns Boolean
    Boolean bCancel
    String[] SelectionValues

     // with non-invoking lists we store and restore the defaults manually
    Send OnStoreDefaults of oSelList

    Set peUpdateMode of oSelList to umPromptNonInvoking
    Set piUpdateColumn of oSelList to 1
    Set psSeedValue of oSelList to sSeed

    Send Popup

    Send OnRestoreDefaults of oSelList

    Get pbCanceled of oSelList to bCancel
    If not bCancel Begin
        Get SelectedColumnValues of oSelList 1 to SelectionValues
        If (SizeOfArray(SelectionValues)) Begin
            Move SelectionValues[0] to sName
            Function_Return True
        End
    End
    Function_Return False
End_Function
