hi,
I have a procedure that has to read a txt file of more than 50,000 lines. I
currently use this code:

// Read a data file in TXT (import)

sFileContent is string
sLine is string
sTiporec is string
sCodpag is string
sCassa is string
sImporto is string
sGiorno is string

IF EDT_PercFile = "" OR EDT_pagamento="" THEN
ToastDisplay("Dati NON Validi",toastLong,vaBottom,haCenter)
ELSE
// Load the file content in memory
ControlVisible(PROGBAR_Horizontal,animScrollBottom,50)

sFileContent = fLoadText(EDT_PercFile)


// Initializes the progress bars to their initial value
PROGBAR_Horizontal = PROGBAR_Horizontal..InitialValue

FOR EACH STRING sLine OF sFileContent SEPARATED BY CR
// Process the line
sTiporec = Middle(sLine, 13, 2)
sCodpag = Middle(sLine, 15, 2)

IF sTiporec = "03" AND sCodpag=EDT_pagamento THEN
sCassa = Middle(sLine, 7, 2)
sImporto = Middle(sLine, 20, 6)
sGiorno = Middle(sLine, 65, 14)

// Increments the value of all the progress bars
PROGBAR_Horizontal++
HExecuteQuery(QRY_insert1,hQueryDefault,sImporto,sGiorno,sCassa,"")
END
END

ListDisplay(COMBO_Combobox, taReExecuteQuery)


TableDisplay(TABLE_QRY_TabTrasn,taReExecuteQuery)



LooperDisplay(LOOP_QRY_TotCassa,taReExecuteQuery)


ControlInvisible(PROGBAR_Horizontal,animScrollBottom,50)

ToastDisplay("FATTO",toastShort,vaBottom,haCenter)



END


but if the file were bigger I could have problems? are there better methods?
