Hi,

@blastit.fr : your code missing leading zero as per OP output example.

Code:
awk 'NR==2{split($0,a)} {printf"%s ",$1;for(i=2;i<=NF;i++) if ( $i==0 ) { printf"%02d ",a[i-1] };print " "}' file

Gives output:
Code:
JKSJM01 09 21 22 23  
JKMSC1 06 21 22 23  
SRIMSC3 04 21 22 23  
SRIMSC2 21 22 23  
SRGMSC1 21 22 23  
JKGJM01 21 22 23  
HRSAM02 21 22 23

If you want entire line with all the fields and you want 02,03 instead of 3, please try the below one and modify as per your need.

Code:
awk 'NR==2{split($0,a)} {for(i=2;i<=NF;i++) if ( $i==0 ) { $i=a[i-1] }}1' file

Gives output:

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
