Read text file from PC one line at a time

[q4u]

Hi,
Need something similar to a READ DATASET but for the PC...
Everything I've come across seems to read the whole file into an internal table at one go.

Thanks.

Why do you need read the file only one line at a time?

[q4u]

'cause i'm a sadist..

[MattG]

You're trying to code this, so you must be a masochist

[q4u]

So I'm getting the distinct impression that it's not possible then...

Read the file in one go, using the standard upload, then write it to the appserver. Then read it from the appserver a line at a time. Alternatively, use ftp, or other file transfer means, to get it to the appserver.

If you would explain WHY you want to read it a line at a time, you might get more help.

Maybe the functional consultant wants it done that way.
...and functional consultant always knows best...

Well.

Just defer the reading of the uploaded text till later.

Stick it all into a table and then Loop around (That's reading it one line at a time), or even use READ TABLE ..... INDEX and just keep incrementing the index. If said functional consultant asks if you are reading it one line at a time just point to the code and say with conviction 'YES'.

Here's how you turn sadistic - this will really hurt the person that asked for it

Code: Select all

DO.
* Call file open dialog
* Call file upload (to internal table)
* Delete all lines in the internal table except the one matching the index of the current DO loop
* If all lines deleted --> Exit
* Read internal table index 1 - move line to other internal table
ENDDO.

* Now process your other internal table

When you're asked why they have to process the file open dialog so many times, just say 'That's what you asked for'

No. The functional consultant is always a loony, who's best not let out on their own. Anyway, what self-respecting functional conslutant even knows what a line in a file is?

A true functional consultant will notice it and say: "you're still reading the complete file in 1 go!"

Best to ask for seperate files with only 1 line in it.

[m@t]

You could write some kind of OLE program to split the file into seperate lines, I suppose.

If the file were an excel, you could read row 1 and then delete row 1. Or is that to obvious? I didn't see that you said what format the file was in.
