20 char lines from long string

[apache7]

Gurus,

Being new to AWK, is there a way to take a very long string (over 2048) and create 20 character lines from it? I have a sample string that look like this:

ZP~19206-3*PAS~G~~~~LYC.RRAAE LXXPCLEAR,MODE*PO1~71~30~R EA~9.45~PE~BP~TK21280Y~VP~2328RY*PWW~V~~~~LDWLIXXT*PQA~8~150~RR~(.09~PE~BP~DK23252Y3~SS~21877Y3*

and would like to create something like this:

ZP~19206-3*PAS~G~~~~
~LYC.RRAAE LXXPCLEAR
,MODE*PO1~71~30~R EA
~9.45~PE~BP~TK21280Y
etc...

This string is read in from a file that has no control characters.

Thanks,

Henry

Or a quick awk version:

function printCnt(line,cnt, xx) {
xx=1
  do {
        for (xx=1 ; xx <= cnt ; xx++) {
            printf(&quot;%c&quot;,substr(line,xx,1))
        }
        line = substr(line,xx,(length(line) - xx))
        #printf(&quot; Line length %d\n&quot;, length(line))
        printf &quot;\n&quot;
     } while (length(line) > 0) 
}


{

        printCnt($0,20)
}
