Save textlines to respective variables

[(_osd_)]

Hello!
I have a textfile called "abc.tmp" and it has 500 lines, in every line is one number.
I want every number to be saved in a variable that is respective to the line it got from, so:

These are the first 5 lines of "abc.tmp":
3
4
0
2
1

And I want the first line (3) to be saved to mvm1,
the second line (4) to be saved to mvm2,
the third line (0) to be saved to mvm3,
the fourth line (2) to be saved to mvm4,
the fifth line (1) to be saved to mvm5,
...

So that all 500 lines of the file are in mvm1 to mvm500. How can you do that?

Yes you can do that. FINDSTR /N prepends a line number to each line, separated with a colon. You can process this output using FOR /F.
untested:

Code: Select all

for /f "tokens=1* delims=:" %%i in ('findstr /n . "abc.tmp"') do set /a "mvm%%i=%%j"

Note: You should avoid that! Better process the lines directly in the loop.

@AGerman Thanks, it works! Why is that better though?

- Loading variables into the process environment takes time.
- The bigger the environment the worse the performance of you script.

Although I don't know your final goal. Thus, I don't know if it would be even possible to work with the FOR variables directly in the body of a loop.

@aGerman Ok... So how can I do that?

As I said - I don't know your final goal. Without having a crystal ball ...

Code: Select all

for /f "tokens=1* delims=:" %%i in ('findstr /n . "abc.tmp"') do (
  echo do something with %%j in line %%i
)

or simply

Code: Select all

for /f "usebackq delims=" %%i in ("abc.tmp") do (
  echo do something with %%i
)
