| jasonwoodland | OPEN command problemI open a file and say I want to delete line A% in that file, how do I do it? I'm making a planner for my Uncle.. as a Christmas present.. So I only got another 30 minutes to solve it. Thanks | 2008-12-24 | 7:26 AM |
| Brandon | Re:OPEN command problemWell I would load all the lines into an array. Then I'd put them back into the file, without the line you want to erase. | 2008-12-24 | 8:58 AM |

The way I do it is you create a new file by reading the original. So let's say your file is "LIST.TXT" and then you do OPEN "LIST2.TXT" FOR OUTPUT AS #2. Next read a single line of the first file, keep a counter of which line you're on and when you reach the line you want to delete, don't write it to LIST2.TXT. Then just delete LIST.TXT and rename LIST2.TXT to LIST.TXT. | 2008-12-24 | 11:42 AM |
| jasonwoodland | Re:OPEN command problemThanks! I tried but no luck, want the code? not much of a gift, more a job, lol. I think I'll just leave the delete command out for the time being. | 2008-12-24 | 2:13 PM |
| SonicBrit | Re:OPEN command problemGoing off of what was said above.
I havent tested this code but it would seem right to me.
This is also assuming you dont want more then 32767 lines in the file if you need more use a & on l and cl instead of %
sub deleteline(f$,l%)
open f$ for input as #1
open "file.tmp" for output as #2
cl%=1
do
line input #1,a$
if cl%l% then
print #2,a$
end if
cl%=cl%+1
loop until eof(1)
close #1
close #2
kill f$
name "file.tmp" as f$
end sub
Let me know if it works or not | 2008-12-24 | 3:08 PM |
