Thanks for the explanation, Jeb!

Thanks Penpen and Dave! In the second example, multiple parameter separators (, ; = <SP> and <TAB>) are indeed replaced with a single space… but not dots. Note that if you quote the string, any leading whitespace and the opening quote itself will be stripped away and the rest of the string will be d...

Thanks Penpen…

Edit: Please read revised code.

Hi All!

Below is an alternative technique for trimming leading and trailing spaces and tabs from a string…

Edit: Please read revised code.

Dear DosTips, I came across something puzzling while researching an alternative method of trimming whitespace (spaces and/or tabs) from the head and tail of a string. To trim any whitespace on the left of a string, simply do this: for /f "tokens=*" %%a in ("%string%") do set &quo...

Hello Sambasiva!

I recommend the find or findstr prompt issue topic. See my contribution at the end.

If you have any further questions, don’t hesitate to ask.

Hello Flora! This line of code is a clever but ugly hack: SET v=%v:;=&rem.% It has the effect of discarding everything in the string after the first occurrence of semi-colon (inclusive). It is the opposite of: SET v=%v:*;=% which removes everything before the first occurrence of a semi-colon (se...

Hi Again! I tinkered with your version of the FTP script and eventually got it to work: @Echo Off & setlocal enableextensions Set "FtpCommand=ls" Call:extractFileSection "[Ftp Script 1]" "-">"%temp%\%~n0.ftp" Set "FileList=" For /F "Delims=&...

Hello VVomble!

Um… what’s wrong with… ?



Or am I missing something? And why are you using set /p? What are you trying to achieve? Please explain your task in more detail.

Hi Again!

Please post your source code. Trim comments and remove usernames and passwords. But one thing I did notice—and this is a long shot—is a missing quote before the ls command.

Good luck!

Hi CastorTroy! FindStr regular expressions are different from wildcard patterns. Try something like this: set FindStrArgs=/x "..*\...*" The above should output only filenames containing at least one dot. If it doesn’t, let me know. If that isn’t what you need, again get back to me and we’l...

@npocmaka_: Welcome to DosTips! @Squashman: You’re absolutely right, as usual. I overlooked this line: SET "z1=%~z1" Dave had said previously that one solution would be to use delayed expansion, so I made a link where there was none and confused !1z! in Endoro’s snippet with the erroneous ...

@Endoro: Thanks for the revised code! It never occurred to me that parameters could be referred to as “!~z1!” using delayed expansion. I don’t remember seeing it used before. I’ve seen “!%~1!”plenty of times, but that’s a whole other box of crayons. @Dave: Thanks for the great explanation. It makes ...

Hi Taripo! DOS 6.22 programs should run without any problems under Windows 98, or am I missing something? If you’re trying to execute an old DOS program under XP or higher, try right-clicking on it, selecting Properties from the pop-up menu, and click on the Compatibility tab… although I doubt if th...
