Selec Top(5000) in DME call

How do I modify the code below to select or return top (5000) records?

Another option is to return records of three months ago from today's date. How do I modify to achieve it?

var sDME = "?PROD=" + vProdLine;
 sDME += "&FILE=ZAP161DATA";
 sDME += "&FIELD=COMPANY;VENDOR-NUMB;VENDOR-NAME;INVOICE-NUMB;INVOICE-DATE;PAYMENT-DATE;";
 sDME += "PAYMENT-CODE;PAYMENT-NUMB;CASH-CODE;REMIT-TO-CODE;PAYMENT-AMT;DISCOUNT-AMT;NET-PAY-AMT;"
 sDME += "EMAIL-ADDRESS;EMAIL-SNT-DATE;" 
 sDME += "EMAIL-ADDRESS;EMAIL-SNT-DATE;RUN-SEQUENCE;RUN-DATE;RUN-TIME;" 
 sDME += "PROC-STAT-FLAG;" 
 sDME += "&MAX=99";
 
 if (parmtype == "V")
 {
        sDME += "&INDEX=ZAPSET6";
       sDME += "&KEY=" + parmVenNumb + "=" + parmRemit + "==";
  
       if (parmRemit != "")
             sDME += "&SELECT=PROC-STAT-FLAG^%21%3DNEW%26PROC-STAT-FLAG^%21%3DREST";
       else
             sDME += "&SELECT=PROC-STAT-FLAG^%21%3DNEW%26PROC-STAT-FLAG^%21%3DREST%26REMIT-TO-CODE^%3C%3D0";
 }
 if (parmtype == "D")
 {
       sDME += "&INDEX=ZAPSET9";
       sDME += "&KEY="+ parmHistDate +"===";
       sDME += "&SELECT=PROC-STAT-FLAG^%21%3DNEW%26PROC-STAT-FLAG^%21%3DREST";
 }

Thanks
