Double the \\ or for paths use / since cdshell doesn't care and you don't have to do anything to escape them.

so either (using your example):

CODE

set mnuimg = "\\images\\menu\\menu.img"

CODE

set mnuimg = "/images/menu/menu.img"

Straight from the Documentation at cdshell.org

CODE

Print C S script.csm
print [l/c/r] <message>
The print command will display a user specified message out on the screen.

The l, c, and r keywords specify left, center, or right justification respectively. The message is aligned to the left by default. If left justification is used, the message will be displayed beginning at the current cursor position. If center or right justification is used, the current cursor position is adjusted as necessary to align the text before the message is displayed. If the message contains lines longer than 80 characters, then it will be displayed in 80-character segments until the remainder is small enough to justify.

The message must be delimited by quotes ("). Any of the escape sequences listed below can be used in the message, however \t may only be used in center or right aligned messages.
\\ Backslash
\" Double-quote character
\n Newline
\t Tab (see tabSize variable)
\ac Change to center alignment and begin a new line.
\al Change to left alignment and begin a new line.
\ar Change to right alignment and begin a new line.
\c(#) Change color. The color in parenthesis can be decimal or hex.
\c## Change color. ## must be two hex digits.
\cxx Change to the default text color.
\cXX Change to the text highlight color.

QUOTE

For each time you assign a string to a variable that you want to print out, you actually have to double the double \\. But then that variable will have double quotes in the string if you want to do something like show the gif or run the command.

Try this code:

CODE

set mnuimg = "\\\\images\\\\menu\\\\menu.img"
print "$mnuimg"
print "\n"

set mnuimgdir = "\\\\images\\\\menu"
set mnuimg = "$(mnuimgdir)\\\\menu.img"
print "$mnuimg"
print "\n"

set mnuimgdir = "\\\\\\\\images\\\\\\\\menu"
set mnuimg = "$(mnuimgdir)\\\\menu.img"
print "$mnuimg"
print "\n"

The first one prints what you would want (or expect):

CODE

\images\menu\menu.img

The second does not print what you would want (or expect):
I expected this one to print imagesmenu\menu.img

CODE

magesenu\menu.img

The third one prints what you would want:

CODE

\images\menu\menu.img

The problem is that you have to double the quotes for every time you would nest and assign a variable, you have to leave enough \ so that the print only picks up a '\\' where you want it to.

However, AFAIK (and I actually haven't tested this), you now cannot use any of those variables to do path related things, so you can't use them to actually chain a bootloader or run a diskimage.

Use a / instead of \ for path related things and you will be just fine.

Hope this helps.

thanks

your last topic have help me very well and i find what i would.

this my result :

QUOTE

set mnuimg = "\\\\images\\\\menu\\\\menu.img"
print "$mnuimg"

result : \images\menu\menu.img
and now :

QUOTE

set mnuimg = "\\images\\menu\\menu.img"
set commandline = "\\images\\menu\\startup.bat"

bcdw boot $mnuimg $commandline

result : bcdw boot on the image and at the end he pass the command line to start the batch. This works perfectly.

Now my UBCD is fully updated with cdshell 2.1.4 and BCDW 2.0a1 and all works

thanks again BastCyric for your help
