Re: System Command Not Executing

Hi Michael,

Out of curiosity, do the date commands show up if you free some of the arrays?

That is, if you add a delete command:

maxt=new((/365*nyr+5,302,121/),float)
mint=new((/365*nyr+5,302,121/),float)
pcp=new((/365*nyr+5,302,121/),float)

system("date")

delete(maxt) ; or, if you have V6.0.0, delete([/maxt,mint,pcp/])
delete(mint)
delete(pcp)

snowd=new((/365*nyr+5,302,121/),float)
swe=new((/365*nyr+5,302,121/),float)

system("date")

---
What kind of system is this on and how much memory do you have?
