Oooops....I forgot about the length being augmented to that of the longest.

Need to right-justify, then pick the last 9 char's and then concatenate...

>> c=strjust(char(D.acct));
>> D.newaccdt=cellstr( ...
[repmat('4412',6,1) strjust(c(:,end-8:end),'left')])
D =
acct newaccdt
'154045001' '4412154045001'
'926665001' '4412926665001'
'615017' '4412615017'
'1976936151' '4412976936151'
'801700' '4412801700'
'4506702001' '4412506702001'

OK, now we got the right last N (=9) characters.
