txt or .dat files

[andy]

if I have a txt file like this


1,1,1,1,1,1
1,2,3,3,2,1
1,4,4,3,4,1
1,3,4,6,5,1
1,1,1,1,1,1


how can I open this file change middle 4 on the 3rd line to a 7
like this

1,1,1,1,1,1
1,2,3,3,2,1
1,4,7,3,4,1
1,3,4,6,5,1
1,1,1,1,1,1

without rewritting the entire file

You can, but it involves some calculations and opening the file as binary. Why don't you just create a binary file with direct access?

... and if that's too complicated, what's wrong with re-writing the whole file with one number change anyway? (depending if it's a small file, of course...)

[andy]

the idea was so that I didn't keep it in an array but held the numbers in the file

Then you're best using what nath said

Look up the QB help for GET, PUT and BINARY file mode.
