h2a for Hex to ASCII (ex: number 12 --> char "C")
a2h for ASCII to hex (ex: char "D" --> number 13)

$ awk -vs=00E011223300 'BEGIN{split("123456789ABCDEF",h2a,"");;h2a[0]="0";for(n=0;n<=15;n++)a2h[h2a[n]]=n}function hex_add(x,A){R="";for(n=length(x);n>0;n--){N=a2h[substr(x,n,1)]+A;A=N>15?1:0;R=h2a[N%16]""R}return R}{print $1,s;s=hex_add(s,1)}' FILE
