Hi rdrtx1,

I tried method -

Code:
$ cat sample.txt
sunilbassi031012345678901234567890123456789
sunilbassi03101234567890123456789
sunilbassi0310123456789

Code:
$ cat scema.txt
LASTNAME 5
FIRST-NAME 5
AGE 3
PHONE1 10
PHONE2 10
PHONE3 10

and the method which we discussed -

Code:
$ awk '
> NR==FNR {if (NF==2) field[++fc]=$2 ; next}
> { el=$0; cc=1; for (i=1; i<=fc; i++) {$i=substr(el,cc,field[i]); cc+=field[i]}}
> 1
> ' OFS=, scema.txt sample.txt
sunil,bassi,031,0123456789,0123456789,0123456789
sunil,bassi,031,0123456789,0123456789,
sunil,bassi,031,0123456789,

outcome doesn't have two commas for last record. Can you please look into this and confirm.

Seems like for the short last line there should be two trailing commas (because it cares) or none (because it does not care and they are a waste).
