proc expand data=XXX out=XXX method=none;
convert high = high1 / transformin=(movmax 12 trimleft 10);
I want to get the Maxmium obs from the most recent 12 obs in the moving windows. But I want to skip the most recent 1 observation. In fact I use 1-11st obs, while skipping 12st obs. How to code it?

I'm new to support SAS comunity. Hope it is not too late.
To skip n first observations use the FIRSTOBS=(n+1) option of input data set, that is:
proc expand data=XXX(firstobs=2) etc.
