String manipulation

I want to do the next

"I don't want to go school
because I'm sick today."

I want to join these two line but only when the first line is not more than 20 characters
and ended whit nothing or a comma and the second line not more than 15.
The 20 and the 15 can be change in the script.
I know how to join two lines but not how to count this.
thank you

awk

Hi,
Try this one,
Code:
awk -v inpf=35 -v inps=30 '{a[NR]=$0;}END{for(i=1;i<=NR;i++){f=length(a[i]);s=length(a[i+1]);if(f<inpf && s<inps && s!=0 && f!=0){ORS="";}else{ORS="\n";}print a[i];}}' file

Cheers,
Ranga:-)

Try:
Code:
awk '1;length<=m && /[[:word:][:space:],]$/ && getline p{print (length(p)<=n?FS:RS) p}{print RS}' m=20 n=15 ORS= infile

for anusurya
I have the errors
line 1: =: order not find
line2; fault near unexpected symbol 'FILE'
line2: `open (FILE ,"$join") or $rc =101;'
I don't understand the first line and I don't see where I must give the name of my file inside your script.
But anyway thanks for the help

Try this class instead:
Code:
awk '1;length<=m && /[[:alnum:][:space:],]$/ && getline p{print (length(p)<=n?FS:RS) p}{print RS}' m=20 n=15 ORS= infile

Does that work?
