Print Lines between two regexes

Hi I have a file like this

Quote:
SQ kkk m99029 wwwAV
qqqq aaaa 111
sssss qqq 222
ffff gggg 22254
//
AS
DS
SQ ooo l9909 qqqqa
aaa ssss 333
222 aaas hhh
//
I need to delete all the lines between SQ and // and not the lines containing them.

So the desired output should be

Quote:
SQ kkk m99029 wwwAV
//
AS
DS
SQooo l9909 qqqqa
//
I tried by using flip-flop operator
Code:
perl -wlne 'print if !(/SQ/../\/\//)'

But its not printing the lines containing regexes.

Thanks in advanceSmilie

NAME
ppmtopgm - convert a portable pixmap into a portable graymap SYNOPSIS
ppmtopgm [ppmfile] DESCRIPTION
Reads a portable pixmap as input. Produces a portable graymap as output. The output is a "black and white" rendering of the original image, as in a black and white photograph. The quantization formula used is .299 r + .587 g + .114 b. Note that although there is a pgmtoppm program, it is not necessary for simple conversions from pgm to ppm , because any ppm program can read pgm (and pbm ) files automatically. pgmtoppm is for colorizing a pgm file. Also, see ppmtorgb3 for a different way of converting color to gray. And ppmdist generates a grayscale image from a color image, but in a way that makes it easy to differentiate the original colors, not necessarily a way that looks like a black and white photograph. QUOTE
Cold-hearted orb that rules the night Removes the colors from our sight Red is gray, and yellow white But we decide which is right And which is a quantization error. SEE ALSO
