Fra SAS til ASP

Jeg har følgende fra en SAS makro, som jeg skal bruge i ASP - er der nogen, der kan lave det om for mig?
(så vidt jeg kan gennemskue, så er der noget syntaks ifb. med brugen af mod)
<var1>
maaned = int((mod(19*mod(&aar,19)+int(&aar/100)-int(int(&aar/100)/4)-int((int(&aar/100)-int((int(&aar/100)+8)/25)+1)/3)+15,30)+1-7*int((mod(&aar,19)+11*mod(19*mod(&aar,19)+int(&aar/100)-int(int(&aar/100)/4)-int((int(&aar/100)-int((int(&aar/100)+8)/25)+1)/3)+15,30)+22*mod(32+2*mod(int(&aar/100),4)+2*int(mod(&aar,100)/4)-mod(19*mod(&aar,19)+int(&aar/100)-int(int(&aar/100)/4)-int((int(&aar/100)-int((int(&aar/100)+8)/25)+1)/3)+15,30)-mod(mod(&aar,100),4),7))/451)+114)/31);
</var1>

og

<var2>
dag = mod(mod(19*mod(&aar,19)+int(&aar/100)-int(int(&aar/100)/4)-int((int(&aar/100)-int((int(&aar/100)+8)/25)+1)/3)+15,30)+mod(32+2*mod(int(&aar/100),4)+2*int(mod(&aar,100)/4)-mod(19*mod(&aar,19)+int(&aar/100)-int(int(&aar/100)/4)-int((int(&aar/100)-int((int(&aar/100)+8)/25)+1)/3)+15,30)-mod(mod(&aar,100),4),7)-7*int((mod(&aar,19)+11*mod(19*mod(&aar,19)+int(&aar/100)-int(int(&aar/100)/4)-int((int(&aar/100)-int((int(&aar/100)+8)/25)+1)/3)+15,30)+22*mod(32+2*mod(int(&aar/100),4)+2*int(mod(&aar,100)/4)-mod(19*mod(&aar,19)+int(&aar/100)-int(int(&aar/100)/4)-int((int(&aar/100)-int((int(&aar/100)+8)/25)+1)/3)+15,30)-mod(mod(&aar,100),4),7))/451)+114,31)+1;
