JOSS - Sample Program

Sample Program

1.1 Demand p,q. 1.2 Stop if q<0 or r(q,2)=0. 1.3 Set a=1. 1.4 Do part 2 while q>1 and a~=0. 1.5 Type a in form 3. 1.6 Stop. 2.1 Do part 20. 2.1 Do part 11 if p<0. 2.2 Do part 12 if p>=q. 2.3 Do part 13 if p=0. 2.4 Done if a=0. 2.5 Set p=p/4 while r(p,4)=0. 2.6 Do part 14 if r(p,2)=0. 2.7 Do part 20. 2.8 Set a=-a if r(p,4)=r(q,4)=3. 2.9 Set s=p, p=q, q=s. 2.95 Do part 20. 11.1 Set a=-a if r(q,4)=3. 11.2 Set p=|p|. 11.3 Do part 20. 12.1 Set p=r(p,q). 12.2 Do part 20. 13.1 Set a=0, p=1, q=1. 14.1 Set a=-a if r(q,8)=3 or r(q,8)=5. 14.2 Set p=p/2. 20.1 Type p, q in form 1 if a=1. 20.2 Type p, q in form 2 if a=-1. Form 1: " L(%.0f,%.0f) =" Form 2: " -L(%.0f,%.0f) =" Form 3: " %.0f\n"

Note that this is not an original sample, but rather one from a modern simulator. There are some syntactic differences from the original JOSS language.
