>Hello all;
>I wrote a prg that opens a text file, reads each line, parses the line and writes it into another file. the program works fine but it takes to long.
>is there a method that i can accomplish this quicker.
>A file that is about 250,000 lines takes almost 2 hours to process. Below is my prg and a few lines of the data from the input file.
>the program creates a new line after every tilde.
>
>the parameter are the file handles created with a Fopen() and fcreate()
>
>PARAMETERS gnInFile, gnOutFile
>LOCAL lnEnd,lnStrt,lnLoop,lcString
>
>lnEnd = FSEEK(gnInFile,0,2) && end of file
>lnEndLoop = lnEnd + 1
>lnStrt = FSEEK(gnInFile,0) && begining of file
>lnLoop = 0
>lcString = FGETS(gnInFile,64)

>FOR lnLoop = 1 TO lnEndLoop
> * lnLoop = FSEEK(gnInFile,0,1)
