Testing a string for imbedded blanks 1

[RPrinceton]

Hi All,
Let's say a field contains "abc def". I want to test this field for imbedded blanks...in this case the blank is contained in position 4. I suppose I could use a "for" construct, but I suspect in Perl there is an easier method. Please advise. Thx in advance.
Regards,
Randall Princeton

the index function is your friend

if (index $mystr, " " != -1) {
  print "space contained in $mystr";
}

Or use a regex:

$mystr =~ /\s+/ && print "space contained in $mystr";

 

[cntr]

Ruby:

mystr = 'abc def'
puts "Space contained in mystr" if mystr =~ /\s/

If by 'blanks', you mean ordinary spaces, PaulTEG's code will do that. If you also want to take into account other 'blanks' such as tabs and newline characters, go with mikevh's, since I suspect that you're probably unwilling to break into Ruby in mid-program.
