Hello,

I used to run the following lines of codes in FPW 2.6 , it took less than 1 minute to complete the process but with VFP7 it's more than 8 minutes for the same data range , please help me to identify the causes of slow process.

Thanks in advance,
PP

set strictdate to 0
select tmpperf
go top
do while !eof()
select CUSTWAIT
go top
store 0 to stand1, sample1, stdm, smpm,stdy,smpy
do while !eof()
if airport=tmpperf.airport and carrier=tmpperf.carrier and loc_code = alltrim(tmpperf.cfield1)
stand1=stand1+iif(m_stand='P'and event_date >=m.from,1,0)
sample1=sample1+iif(m_stand#'-' and event_date >=m.from,1,0)
stdm=stdm+iif(m_stand='P' and event_date >= m.prev_month,1,0)
smpm=smpm+iif(m_stand#'-' and event_date >= m.prev_month,1,0)
stdy=stdy+iif(m_stand='P' and event_date >= m.prev_year,1,0)
smpy=smpy+iif(m_stand#'-' and event_date >= m.prev_year,1,0)
endif
skip
enddo
select tmpperf
replace cfield2 with allt(str(sample1)),cfield3 with pct(stand1,sample1),;
cfield4 with pct(stdm,smpm),cfield5 with pct(stdy,smpy),;
cfield1 with iif(seek(allt(tmpperf.cfield1),"QTLOCAT"),QTLOCAT.NAME,"??????")
skip
enddo
