Help with Labelling-please

Hi, trying to label each of the individual graphs (ifrs) based on a 3 variables VARS/llp. What I please need is to have a heading for each of the computed graphs.
The code is a modified version of the original Jorda (2005) where the results of the VAR have been removed.
The code is below:
Thanks

If I understand you correctly, you want to replace the graph instruction in the inner loop with

compute header="Response of "+varlabels(1,i)+" to "+shocklabels(1,j)
graph(row=i,col=j,number=0,min=%minimum,max=%maximum,header=header) 3

(or something like that with the compute header=...)
