Purpose:
Reading data from listscreen into array.
In Below example data from column "Document" of listscreen is read into an array by using position in set command.
LiquidUI Code:
/////////////////////////////////// RVKRED01.E0120.sjs ////////////////////////////////
pushbutton( [TOOLBAR], "scroll ",{ "process": z_readfromlist }); // pushbutton to call function
function z_readfromlist(){ // function to reading data from listscreen and assign it to array
z_doc = []; // array to store data
lfvrow = 1;
onscreen 'RVKRED01.0120'
SCROLL_NEXT:;
enter("/scrolltoline=&V[lfvrow]"); // scroll the list vertically
onscreen 'RVKRED01.0120'
enter("/hscrollto=0"); // scroll list horizontally
// goes to end of function when end of listscreen is reached
if(lfvrow >= _listlastvisiblerow){
goto END;
}
START:;
lfvrow = _listfirstvisiblerow;
llvrow = _listlastvisiblerow;
z_row = 3;
LOOP:;
// column data read into variable using position on screen
set("V[doc_val]","&#["+z_row+",30]");
z_doc.push(doc_val); // data from variable pushed into array
lfvrow = lfvrow+1;
if(lfvrow <= _listlastvisiblerow){ // fetches data from next row
z_row = z_row+1;
goto LOOP;
}
else{ // navigates to scroll code if end of screen is reached
goto SCROLL_NEXT
}
END:;
for(j=0;j<z_doc.length;j++){ // display array elements on cornelius output window
println("document number at z_doc["+j+"]="+z_doc[j]);
}
}
You can view data from document column of listscreen on cornelius output window.
