I have a CSV data file that can contain a variable amount of lines. I need to pull data from the last two lines, which are typically line 20 and 21. When there are additional fields before these two, it may move them to 22 and 23, 24 and 25, etc.

I've asked our DB Analyst to place indentifier characters before these two fields. Is there an expression that I could use to say, 'when you see this character, print the data after it in this location'?

Thanks in advance for your help.

I think something like a For loop in PressTalk will help you here. Use it as a condition to set the line number for a data selection:

define(&line,integer,1)
define(&target,string,'target')
define(&hereitis,integer,0)

for(&line,1,1,&lpp)
if(@(&line,1,6)=&target)
&hereitis:=&line
exit()
endif()
endfor()
