if!HOut() {
CALLWD("Screen,ScreenToFile");

}
// In Pascal
HReadFirst("CUSTOMER","NAME");

Syntax
Screen,FileToScreen()
Remarks
  • Screen, FileToScreen does not read the file. The controls are initialized with the record loaded in memory. A record must necessarily be loaded in memory before calling this function.
  • In case of direct link, Screen,FileToScreen transfers the value of the items for the record loaded in memory into the linked controls, without performing any read operation.
  • In case of link with search in a linked file, the search is performed in the linked file before transferring the value of the items into the control.
