Trimming spaces from a variable

Hi guys,
when I take substring of a particular data using this command
var=substr($0,11,10)
it comes with spaces, when I am trying to trim the spaces it is not allowing me to do that.
Can you please help me out on that.
As I have to reverse the output of the variable also.

a=substr($0,11,10)
a1=`echo "${a}" | sed 's/ *$//'`

then it give me this error
The error context is
>>> a1=` <<<

NAME
libcaca-style - Libcaca coding style General guidelines A pretty safe rule of thumb is: look at what has already been done and try to do the same. o Tabulations should be avoided and replaced with eight spaces. o Indentation is generally 4 spaces. o Lines should wrap at most at 79 characters. o Do not leave whitespace at the end of lines. o Do not use multiple spaces for anything else than indentation. o Code qui fait des warnings == code de porc == deux baffes dans ta gueule C coding style Try to use short names whenever possible (i for indices, w for width, cv for canvas...). Macros are always uppercase, variable and function names are always lowercase. Use the underscore to separate words within names: #define BROKEN 0 #define MAX(x, y) ((x > y) ? (x) : (y)) unsigned int x, y, w, h; char *font_name; void frobulate_every_three_seconds(void); const is a suffix. It's char const *foo, not const char *foo. Use spaces after commas and between operators. Do not use spaces after an opening parenthesis or before a closing one: a += 2; b = (a * (c + d)); x = min(x1, x2, x3); Do not put a space between functions and the corresponding opening parenthesis: int function(int); A space can be inserted after keywords such as for, while or if, but consistency with the rest of the page is encouraged: if(a == b) return; if (p == NULL) Do not put parentheses around return values: return a + (b & x) + d[10]; Opening braces should be on a line of their own, aligned with the current block. Braces are optional for one-liners: int function(int a) { if(a & 0x84) return a; if(a < 0) { return -a; } else { a /= 2; switch(a) { case 0: case 1: return -1; break; default: return a; } } } C++ coding style Nothing here yet.
