Hi, sorry if someone has posted a topic about this already. I've written the following loop:


%series_list = "econ1 econ2 econ3"
For %portfolio port1 port2 port3
	For %model test1 test2 test3 test4
		%temp= "%" + %portfolio + "_" + %model

		wfopen  {%temp}
		%current_wf1=@wfname

		For %series {%series_list}
			
			Pageselect New_Port
			if @isobject(%series)=1 then
				copy(overwrite) {%current_wf1}::New_Port\{%series} {%wf1_name}::Economics\{%series}_{%portfolio}_{%model}
			else
			statusline %series does not exist in workfile %temp
			endif
			
		next
		wfuse {%current_wf1}
		wfclose
	next
next

where port1_test1 etc are pre-defined string variables containing the file name and path of previously saved workfiles.

The problem I'm having is that when the code runs the final iteration of the 3rd loop, it tries to run it again, replacing the control variable %series with econ3 and so the program falls over.

I've tried resetting %series="" at the end of the loop but that causes a similar error.

Hope I've explained my problem well. Any ideas??

I cannot see anything particularly wrong with the loop structure. Indeed a simple test of the loop structure seems to indicate it is fine:

Code: Select all


create u 10
table a
!i = 1
%series_list = "econ1 econ2 econ3"
For %portfolio port1 port2 port3
   For %model test1 test2 test3 test4
      %temp= "%" + %portfolio + "_" + %model

      For %series {%series_list}
         
		a(!i,1) = %portfolio
		a(!i,2) = %model
		a(!i,3) = %series
		!i = !i+1
         
      next
   next
next
