Hi Jeet,
How it works is more complicated than I can understand, but basically, the
scripting compiler recognises the backslash character as a marker to convert
what immediately follows to a specific character in the ASCII series. Not
sure if you were also asking about what ASCII is, but google will have a bit
to say about that.
Some of the ones I am familiar with are:
"\N" = line feed or character 10
"\R" = carriage return, or character 13
The same 2 characters will be produced by:
"\10" = line feed
"\13" = carriage return
"\34" = quote mark
"\\" = the backslash character itself
This one is particularly interesting, as if you wish to hardcode a file path
in a script, such as "C:\ProgramData\Freedom Scientific\", in the script
you would need to use double backslashes as, "C:\\ProgramData\\Freedom
Scientific\\", so the compiler would produce the actual path you wanted.
"\007" = the separation character, LIST_ITEM_SEPARATOR, used in the function
dlgSelectItemInList. See the entry for that constant in HJCONST.JSH.
When a 0 preceeds a number following the backslash, it changes the way the
script compiler treats the number, but someone else on the list will need to
explain that, as while I can use it, I dont understand it.
"\999" where 999 represents a number in the ASCII series, from 0 to 255,
causes the compiler to produce the character represented by that number.
For example, 65 is the ASCII number for the upper case, A so "\65" will
produce the letter A.
Note, the compiler mostly knows when to stop the conversion.
In my previous example, "\34(", the compiler converts only the \34, and uses
the ( as it is.
When using the line feed in a longer string, such as, "first line\Nsecond
line", to be used in one of the Jaws dialog boxes, the compiler only
converts the \N, and the result on screen is:
first line
second line
Hope this helps,

Thanks, it did the trick but what is \34, is the ascii value?
and why we need include the back slash?
thanks, Jeet
