Re: An example of extreme dynamic variable nesting.

Not on my version of XP ... I also ran your code from this thread and it also crash http://www.dostips.com/forum/viewtopic.php?f=3&t=2851 Build 2600 xp sp2 Interesting... For the latter, do you mean a literal "crash", and was it with the "call :exec" (vs. "call :exec-fa...

unexpected jump

This may well be an xp.sp3 quirk, haven't tried it elsewhere, yet. But it's quite odd. Here's the code... @echo off setlocal disableDelayedExpansion echo. echo * %~n0 { %1 } set /a rearg1 = %1 - 1 if %rearg1% leq 0 goto :done echo * before call :exec %0 %rearg1% call :exec-fail %%0 rearg1 echo ..aft...

Re: An example of extreme dynamic variable nesting.

But it is not possible to build a string with special characters and make a call, the expansion have to be on the last call level. ... Because all carets are doubled by a call, so the parser see ... If the char "&" or "|" is recognized in a call the complete cmd will be canc...

Re: help - prompt for password

If the exe reads the password off its "standard input stream" you may try "echo yourpassword| yourexe". However, if it's reading it directly off the interactive console, or if it's a GUI app with no console whatsoever, that won't work. And, just saying, but I wouldn't hardcode a ...

Re: foolproof counting of arguments

Yet another variation on the same theme... The code below collects all parameters in a temp file, with the stop condition based on the size of the file. Then, it reads the file back in one shot. EDIT: code below has changed vs. the one posted earlier today. At the time I edited, there were no follow...

Re: foolproof counting of arguments

Now I understand why jeb had that # in his REM statement, to protect against /? I've edited my previous post to compensate. Pretty sure I've seen this noted before, though I can't find a reference handy now... One other corner case is that the 'for' loop would save the incorrect %1 when passed %a o...

Re: a little unicode related subtopic

The font makes no difference, except look different on the screen and in screen snapshots (or, worse, look the same for different binary characters depending on the active codepage). Whenever in doubt, check the actual file contents with your favorite binary viewer. I suppose it looks a bit like it...

It might not make any difference, but which font are you using, and do you also get the display that picture shows when you paste it in the command prompt?

Re: foolproof counting of arguments

Here is a clean looking script that safely loads all of the arguments into an arg "array" using the REM trick. Not sure I fully follow the part about exiting and reentrying the doubly redirected () block, yet, but it looks as if it's internally equivalent to individual per-argument redire...

Re: foolproof counting of arguments

It's still not exactly foolproof Example argument (jeb): one^&two"&three simplified: "& or "&" Thanks for that. Somehow thought it couldn't be that easy And it takes down any following parameters as well. Now, I don't think that'd be much of a problem in my parti...

Re: foolproof counting of arguments

Don't think there is much you could do about a string not being closed quoted correctly. If you just have a set of empty quotes then you can check to see if it is empty. So given your example of "" a --- I should have made it more clear that the "---" was part of my comment, not...
