I don't fully understand.
If you need a fixed record size, use printf:
Code:
awk '(NR<=2) {printf "%-24s\n",$0; next} ($1=="B") {printf "%-13s%-11s\n",$1,$2}' file

To change a certain value on the fly, you can use
Code:
{
awk '(NR<=2) {printf "%-24s\n",$0; next} ($1=="B") {$2="yyy"} {printf "%-13s%-11s\n",$1,$2}' header
cat detail
awk '(NR<=2) {printf "%-24s\n",$0; next} ($1=="B") {$2="yyy"} {printf "%-13s%-11s\n",$1,$2}' trailer
} > newfile

NAME
gnutls_record_set_max_size - sets the maximum record size SYNOPSIS
#include <gnutls/gnutls.h> ssize_t gnutls_record_set_max_size(gnutls_session_t session, size_t size); ARGUMENTS
gnutls_session_t session is a gnutls_session_t structure. size_t size is the new size DESCRIPTION
This function sets the maximum record packet size in this connection. This property can only be set to clients. The server may choose not to accept the requested size. Acceptable values are 512(=2^9), 1024(=2^10), 2048(=2^11) and 4096(=2^12). The requested record size does get in effect immediately only while sending data. The receive part will take effect after a successful handshake. This function uses a TLS extension called 'max record size'. Not all TLS implementations use or even understand this extension. RETURNS
On success, GNUTLS_E_SUCCESS (zero) is returned, otherwise an error code is returned. REPORTING BUGS
