Hello JSKOBS,

Glad it worked for you. Could you please go through following and let me know if this helps you.
Code:
awk '($0 ~ /^[[:digit:]]/ && A){            #### Checking if the current line is starting with DIGITS and variable named A is NOT NULL, then perform following statements.
print A;                                    #### printing variable named A.
A=""}                                       #### Nullifying the value of variable A.
{gsub(/^[[:space:]]+|[[:space:]]+$/,X,$0);  #### I am substituting spaces from the starting of the lines and last of the lines here. where gsub means global substitution in awk.
A=A?A OFS $0:$0                             #### Creating variable named A whose value will be current line's value and it will keep concatenating it's own A's value till above 1st condition becomes TRUE where line starting from digits, there we are nullifying it's value.
} 
END                                         #### END section here.
{print A}                                   #### printing the value of A, because last line's A value should be printed here.
'   Input_file                              #### Mentioning Input_file here for awk to be read.

Thanks,
R. Singh
