Scripts in MCR Algorithms

Script for MCR Algorithm to Obtain a Card Number after Scanning a QR Code with a Camera

It is required to register a QR code in the order using an Ipod and a tablet POS.

QR code format:
QRC=<card info>:<var info>

Example:

QRC=123456789:121212

card info - 123456789

var info - 121212

Card code = card info meaning (year ( whole ) + month (1–12) + day).

CODE

That is, if there is a card with the No. 5555, the Card info as of May 13, 2015, is equal to Card

Code(5555)+Year(2015)+Month(5)+Day(13)

5555+2015+5+13=7588

As the result, we shall get the Card code.

function MCR1002183(DeviceSignal: Integer; DeviceIdent: Integer; var Parameter: String): Boolean;

begin

  // for input parameter: QRC=123456789:121212

  Result := False;

  if pos('QRC=',parameter) > 0 then

  begin

    parameter := copy(parameter,5,pos(':',parameter)-5);

    Parameter := IntToStr(StrToInt(Parameter)-(StrToInt(FormatDateTime('yyyy',now))+StrToInt(FormatDateTime('mm',now))+StrToInt(FormatDateTime('dd',now))));

    Result := True;

  end;

end;

CODE

Script for Table Selection

It is required to ensure that, when a customer card is swiped, a table with the number programmed on the card is shown in the order editing window.

function MCR1001882(DeviceSignal: Integer; DeviceIdent: Integer; var Parameter: String): Boolean;

begin

  Result := False;

  { 999table_identifier }

  if pos('999', Parameter) = 1 then begin

    delete(Parameter, 1,3);

    if length(Parameter) > 0 then begin

        gui.showmessage(Parameter);

        RK7.PerformRefObject(RK7.FindItemByCode(rkrefTables, StrToInt(Parameter)))

        Result := true;

    end;

  end;

end;

          'C': t1 := '1100';

          'D': t1 := '1101';

          'E': t1 := '1110';

          'F': t1 := '1111';

        end;

        Res1 := Res1 + t1;

      end;

      Result := true;

CODE

Script for Converting Dec to Oct

Software:

r_keeper 7.5.3.279
SkiBars2

Problem:

PRX KE (PS/2) readers were used for processing SkiBars cards at existing r_keeper 7 stations
new stations have arrived that are equipped with other readers, SRCh125 (RS232)
the clue problem is that the same card is processed differently by these readers

Run a check at the station using MCR Algorithm Debugging

PRX KE (PS/2): 0,41153061004700

SRCh125 (RS232): 0,3684940

The script converts entries of the 0,3684940 type to 0,41153061000000

function MCR1001908(DeviceSignal: Integer; DeviceIdent: Integer; var Parameter: String): Boolean;

var

  i,len, ost1,ost2:integer;

  s,res: string;

begin

  Result := False;

    s:=copy(Parameter,3,9);

    res:='';

    ost1 := StrToInt(s);

    While ost1<>0 do

    begin

      ost2 := ost1 mod 8;

      ost1 := ost1 div 8;

      res := IntToStr(ost2) + res;

    end;
