Untested, but I think you can replace

if fyear==1971{
     by id: replace debtlevel_sim=actual_debtlevel                 
/*start with actual debt-level in 1971*/
else if fyear>1971 & (L.debtlevel_sim+debtissue_sim)<=0 {        /*in  
years following 1971: no negative debt-level*/
     by id: replace debtlevel_sim=0
else {
     by id: replace debtlevel_sim=L.debtlevel_sim+debtissue_sim 

with one line:

by id: replace debtlevel_sim = cond( fyear==1971, actual_debtlevel, max(0, L.debtlevel_sim+debtissue_sim ))
