Did you set FNAME variable to the label of a file on your system?

Quote

There is no echo %fname% instruction in the script. I'm as surprised as you!

&LT;sigh> Still compressing/decompressing files?

The first block of the script count the records in the file

The second block subtracts 30 from the recordcount and either loads the array from the file (recordcount - 30 is negative) or skips recordcount - 30 records before loading the array

The third block lists out the contents of the array

I can't duplicate your error. There may have been an error when you copied/pasted the code into your editor.

Batch code does cloak and dagger. Who knew?

I'll try the code again...But no, it is not compressing then decompressing files.

If you want all the lines in variables remove some of the logic from the posted code:

Code: [Select]@echo off
setlocal
set fname=drive:\path\file.ext

for /f "tokens=* delims=" %%x in (%fname%) do (
call set /a idx=%%idx%%+1
call set array.%%idx%%=%%x
)

for /L %%x in (1,1,%idx%) do call echo %%array.%%x%%

Yes. Hamlet was not a programmer. In the original context it was an XOR that had to have a YES or NO. But the C construct would become -1 if converted directly to a number. What would Hamlet think if we told him the answer is always minus one?Quote

And I said that I DO need a variable for each line. (But atleast my problem is partially done)
