Delete the line started with nondigit or newline character
i want to delete the line which is not started with numeric in vim.

Code:
vim temp.txt

 Volume in drive D is DATA
 Volume Serial Number is 8C52-2055

               7 Dir(s)  10,324,987,904 bytes free

if i go for
Code:
:%g/^\D/d

then it only remove the line which is not started with nondigit but some blank lines are not removed . Could it possible to find line started with nondigit or newline character so that we could remove it at the same instance .
Code:
:%g/^[\D\n]/d

this things is not working as ^ act as a negate character here.
Is there any solution for it.

Thank & Regards
Dina

srec_cosmac(5)							File Formats Manual						    srec_cosmac(5)

NAME

       srec_cosmac - RCA Cosmac Elf file format

DESCRIPTION

       This file takes the form of one or more RCA Cosmac Elf monitor commands, also known as the IDIOT/4 monitor.  Only the change memory command
       (!M) is allowed.

       The general form of the !M command takes the form
	      !Maaaa dd ... dd
       The !M command writes data byte bytes (represented by character pairs dd) into successive memory locations, started at address aaaa.   Spa-
       ces between data bytes are ignored.

       Using the comma (,) line continuation character resumes from the next address in sequence.
	      !Maaaa dd ... dd, dd ... dd

       Using the semicolon (;) line continuation character takes an address on the next line
	      !Maaaa dd ... dd; aaaa dd ... dd

       It is also possible to have the semicolon immediately after the command.
	      !M; aaaa dd ... dd

       All of these forms may be used in combination.

   Size Multiplier
       In general, binary data will expand in size by approximately 2.0 times when represented with this format.

EXAMPLE

       Here is an example Cosmac file.	It contains the data "Hello, World[rq] to be loaded at address 0x1000.
	      !M1000 48656C6C6F2C20576F726C640A
