Thanks, Corona and Don.

Don, while i was reading ur reply to figure out my mistake, i realize tat i<100 was juz a typo, i wanted to set it i<10. Btw, thanks for tis new lesson Smilie I wont quit programming, i feel it is fun to solve problem.

Corona, so i hav check out tis ASCII character set, yea i found tat 1st 16 character of ASCII character r non printable control characters. I wonder if 0 = 0, 1 = 1, 2 =2 and so forth, and '0' = 48, why will it bcome 1 when we minus '1' - '0' and not a non printable control characters? If we add '0' to 1, will it bcome bak '1' or as u said '0' = 48 and bcome 49?? How do dey differentiate it is a character set or an integer??

Sorry everyone who r trying to reply me. I feel tat im annoying, i hope tat u all don mind to answer my question Smilie

GUILT-PATCHBOMB(1)						   Guilt Manual 						GUILT-PATCHBOMB(1)

NAME
guilt-patchbomb - Email a series of commits interactively SYNOPSIS
guilt-patchbomb [-n] [-s] [--in-reply-to <msgid>] [--git] [--subject-prefix <prefix>] [<hash> | <since>..[<until>] | ..<until>] DESCRIPTION
Send a series of commits via email asking for To, CC and other information interactively. OPTIONS
-n Don't send -s Don't add additional repository committer sign-offs to the patch. This allows the sign-off chain to be fully expressed in the commit messages and not changed by the act of sending a patchbomb. --in-reply-to <msgid> Set the In-reply-to header to the specified message id. This allows the patches to be sent as replies to an arbitrary message. --git Generate a patch which uses all the features offered by the git diff format (e.g., rename and copy detection). --subject-prefix <prefix> Rather than using the standard [PATCH] prefix in the subject line, use [<prefix>] instead. <hash> Only the specified revision. <since>..[<until>] Revisions starting from <since> until <until>. The <since> revision it self is NOT included, while <until> is. If <until> is not specified, it is assumed to be HEAD. ..<until> All revisions until the <until> revision (inclusive). AUTHOR
