Hi all! How can I display (or set an array of variables (for example x[cnt])) of first/last n lines from a .txt file? http://www.dostips.com/forum/viewtopic.php?f=3&t=3633 has a solution for reading all lines to variable. One way would be to: 1. count the number of lines 2. sort in reverse (if d...

Dumping the source file first would make it possible to process all values (0-255) (agerman's excelent file dump: viewtopic.php?p=14361#p14361).

Sometimes it is better to do it like this:

The reason FINDSTR is not working is because FINDSTR fails to work with many extened ASCII characters (hex code > 127) if they are used on the command line. If an extended ASCII character such as the " ü " (dependent on your code page) is used on the command line in a search string, then ...

We also have characters that are not in the English alphabet. All you have to do is: - convert the original file from the CP you have in Windows (I have CP1250) to your DOS CP (I have CP852) - then you should be able to enter the letter Brunsbüttel in the DOS window (because it is in your DOS codepa...

Here is another update. Changes: - procedure now determines the required privileges for a user based on %username% system variable - userdata is stored within the procedure (starts with UUUUU (menu data starts with MMMMM) - if %username% does not exist in the database General User is assumed (with p...

Here is a working menu system. Originaly I wrote it in 2000 in DCL on OpenVMS but only now I managed to port it to batch. It displays a word 'menu' infront of the selection if there is a sub menu behind that choice. Currently procedure requires Aacini's cursorpos.exe. @echo off REM -----------------...

Here is an update. I added small letters a-z to the list of available characters. Now the maximum base is 62. Because dos does not distinguish between capital and small letters in variable names: set mapA=10 and set mapa=40 mapping small letters to array does not work. Instead I used a temporary fil...

Based on this Aacini's work http://www.dostips.com/forum/viewtopic.php?f=3&t=5665 here is the converter for converting between decimal numbers and base-N (and vice versa). It even calculates the length (number of characters) of the result. Base-N can be between 2 and 36 (inclusive). Saso @echo o...

Aacini: I tried to understand everything but it looks like I am too blond (though I am not). Please explain the following commands: Why does the command below display each part of the 'map' variable as a separate line (record)? set "map=0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ" for /F "de...

Aacini: thanks alot. Works perfectly.

Hi all! Based on this http://www.dostips.com/forum/viewtopic.php?p=34025#p34025 I decided to change the record offset number and record length number with some encoded information (to minimize a chance of finding the number user enters in the 'record offset' field because I also modifed the searchin...

I am updating my program to maintain a database with 24000+ records. I changed it to INDEXED file (see http://www.dostips.com/forum/viewtopic.php?f=3&t=5552). It works very well (I have 12 fields, demo has only 3 - one of the changes was splitting the first field (record offset+record length to ...

Does it really matter? The flag is far from even coming close to being an accurate representation of the US Flag. Way to many stars and way too many stripes. It's not the US flag it is the fact that I have problems with other command procedures (.cmds) aswell. And it looks like this is the reason. ...
