a=`echo "$a" | sed 's/$/ /g'`
b=`echo "$b" | sed 's/$/ /g'`
echo "$a"
echo "$b"

but this results in the output:
80 and 897

it works when i use
Code:
a='$987'
b='890'

But I cannot use single-quotes in my actual code as the variable values are extracted as strings and are not constant.

Is there any other command or any fix for this ?
I even used 'tr', even that works similar to sed .
Try the way Scrutinizer suggested.
The reason behind for sed cmd not working is,
$ - has special meaning in sed( almost in all regex). so you have to put \ before using the special meaning characters.

Code:
a="\$980"
a=`echo "$a" | sed 's/\$/ /g'`

Cheers,

DBSYM(8)						    BSD System Manager's Manual 						  DBSYM(8)

NAME
dbsym -- copy kernel symbol table into db_symtab space SYNOPSIS
dbsym [-v] [-b bfdname] kernel DESCRIPTION
dbsym is used to copy the symbol table in a newly linked kernel into the db_symtab array (in the data section) so that the ddb(4) kernel debugger can find the symbols. This program is only used on systems for which the boot program does not load the symbol table into memory with the kernel. The space for these symbols is reserved in the data segment using a config option like: options SYMTAB_SPACE=72000 The size of the db_symtab array (the value of SYMTAB_SPACE) must be at least as large as the kernel symbol table. If insufficient space is reserved, dbsym will refuse to copy the symbol table. To recognize kernel executable format, the -b flag specifies BFD name of kernel. If the -v flag is given, dbsym will print out status information as it is copying the symbol table. Note that debugging symbols are not useful to the ddb(4) kernel debugger, so to minimize the size of the kernel, one should either compile the kernel without debugging symbols (no -g flag) or use the strip(1) command to strip debugging symbols from the kernel before dbsym is used to copy the symbol table. The command strip -d netbsd will strip out debugging symbols. SEE ALSO
