More updates finally finished. Turning off firewall and virus scan may have helped. When I did a successful update, I did not realize that more updating was needed for "security and features" as warned in Windows Updates screen. Apparently using sequence codes in batch does not require the registry ...

ShadowThief, thanks for your advice. Windows updated to version 10.0.14393. PC has been rebooted. I do know how or where to find settings that would display more than 16 colors with RGB sequence codes, in the cmd window from batch. Display Settings changes made no difference. Still not resolved. edi...

I have been experiencing issues with my desktop (Win 64 bit) requiring 2 boot-ups because of screen blinking, for several months, and finally I could not boot at all and repair failed many times. Then I used DELL repair tools to reinstall Windows and wipe the hard disk of everything. Now I find that...

Are there not 3 special cases? Adding an asterisk increases the lower count.
Adding a special case for asterisk counts it as a special character. Jerry

Didn't know about irfanview playing audio files and I just hammered this out until it worked. Another part of this scheme could be to sort the playlist in random order before playing. Jerry @echo off setlocal set "musicpath=c:\music\" set "pListpath=%muspath%myplist.m3u" set "prg=c:\program files\ir...

What would be an example command to AutoMenu.bat?
My entry on a Windows 10 PC in the cmd window from the directory where your files are stored c:\AMenu

automenu c:\temp 2- FILE

Environment variable option[ not defined

followed by continuous looping of the error message.
Thanks.

Understood. I thought that a line of code to display %% if found doubled in the string might be helpful.
My thinking was that literal doubled percents, like all other characters, but maybe not quotes, are a target for identification.

aGerman, how does your code, typed out below, display %% for you and not for me? :o c:\Temp\Dosbatch>testAG 88 && Press any key to continue . . . c:\Temp\Dosbatch>type testag.bat @echo off setlocal DisableDelayedExpansion set "str=R#6-O0W9OXRi&FQSf1&ZcBJlwhE886D%%2CZ+-L7B+Z2khH1UG3NbDC&&Xj@TvS!DVEA1...

I did not see %% after running the batch codes. An extra step may be needed to catch double percents. I added other special characters doubled. Quotes are not addressed; an odd number caused an error. Jerry @echo off set "str=R#**6-O0W9OXRi&FQSf1&ZcBJlwhE86D%%2CZ+-L7B+^Z2khH1<<UG>>3NbDC&&Xj@TvS!DVEA...

This produces a similar effect, increasing the window size with each line of text, but the screen is cleared with noticeable flicker before displaying each set of lines.

SB, I tried to join twice and get "MAILER-DAEMON@yahoo.com, Failure Notice, Sorry, we were unable to deliver your message, 510: 5.1.1 That group does not exist."
This was done after setting up an account with my yahoo email account.

String substitution is not case sensitive. Squashman, thank you for that lesson.

I can't see why the code below does not give the results I expect, give one match in a case sensitive comparison. The code represents an issue in a larger script. I'm probably confused and need expert help :roll: Yes, I read /? IF Jerry @echo Off setlocal EnableDelayedExpansion set "string=a" call :...

Thanks for both for the explanations and examples of redirection of the error message. The shorter and safe method, del "%tempFileID%" 2> NUL is the one I'll use. Batch tools in my never-ending project write temporary files to get to the end product, and file removal is done after each temporary fil...

I see this in a post: del file.tmp 2>nul

I delete temporary files using this syntax: IF EXIST "%tempfileID%" DEL "%tempfileID%"
Is there a preferred way to do this?
Thanks.
Jerry
