echo "Number of elements in ARRAY: ${#ARRAY[@]}"
for ((i=0; i<${#ARRAY[@]}; i++))
do      printf "'%s'%d\n" "${ARRAY[$i]}" "$i"
done

which produces the output:
Code:
Number of elements in ARRAY: 16
' '0
' '1
' '2
' '3
' '4
' '5
' '6
' '7
' '8
' '9
' '10
' '11
' '12
' '13
' '14
' '15

and also produces exactly the same results if run by a 1993 or later version of ksh instead of bash.
Yes, that was why I used my original 'hexdump' method as that placed just a single <space> character into each cell.
However RudiC's solution is the one I will use.
The way he creates the array indexing is cool. No amount of Googling gave me that kind of result.
Even my method didn't show up in Google and that is pretty much bullet proof, plus, I knew it would work, but 1920 calls to it would be well OTT.
There is a pointer now though for Google... ;o)
I won't mark as solved yet as others might have bash or maybe even dash solutions too.

Log::Report::Lexicon::PO(3pm)				User Contributed Perl Documentation			     Log::Report::Lexicon::PO(3pm)

NAME
Log::Report::Lexicon::PO - one translation definition DESCRIPTION
This module is administering one translation object. Sets of PO objects are kept in a POT file, implemented in Log::Report::Lexicon::POT. METHODS
Constructors Log::Report::Lexicon::PO->new(OPTIONS) -Option --Default automatic "" comment [] format [] fuzzy false msgid <required> msgid_plural undef msgstr "" or [] references [] automatic => PARAGRAPH Automatically added comments. See addAutomatic(). comment => PARAGRAPH Translator added comments. See addComment(). format => ARRAY-OF-PAIRS|HASH See format(). fuzzy => BOOLEAN The string is not yet translated, some smart guesses may have been made. See fuzzy(). msgid => STRING msgid_plural => STRING msgstr => STRING|ARRAY-OF-STRING The translations for the msgid. When msgid_plural is defined, then an ARRAY must be provided. references => STRING|ARRAY-OF-LOCATIONS The STRING is a blank separated list of LOCATIONS. LOCATIONs are of the form "filename:linenumber", for instance "lib/Foo.pm:42" See addReferences() Attributes $obj->addAutomatic(LIST|ARRAY|STRING) Add multiple lines to the translator's comment block. Returns an empty string if there are no comments. $obj->addComment(LIST|ARRAY|STRING) Add multiple lines to the translator's comment block. Returns an empty string if there are no comments. $obj->addFlags(STRING) Parse a "flags" line. $obj->addReferences(STRING|LIST|ARRAY) The STRING is a blank separated list of LOCATIONS. The LIST and ARRAY contain separate LOCATIONs. A LOCATION is of the form "filename:linenumber". Returns the internal HASH with references. $obj->automatic([LIST|ARRAY|STRING]) Returns a STRING which contains the cleaned paragraph of automatically added comments. If an argument is specified, it will replace the current comment. $obj->comment([LIST|ARRAY|STRING]) Returns a STRING which contains the cleaned paragraph of translator's comment. If an argument is specified, it will replace the current comment. $obj->format(LANGUAGE|PAIRS|ARRAY-OF-PAIRS|HASH) When one LANGUAGE is specified, it looks whether a "LANGUAGE-format" or "no-LANGUAGE-format" is present in the line of FLAGS. This will return 1 (true) in the first case, 0 (false) in the second case. It will return "undef" (also false) in case that both are not present. You can also specify PAIRS: the key is a language name, and the value is either 0, 1, or "undef". example: use of format() if($po->format('c')) ... unless($po->format('perl-brace')) ... if(defined $po->format('java')) ... $po->format(java => 1); # results in 'java-format' $po->format(java => 0); # results in 'no-java-format' $po->format(java => undef); # results in '' $obj->fuzzy([BOOLEAN]) Returns whether the translation needs human inspection. $obj->isActive Returns whether the translation has any references, or is the header. $obj->msgid Returns the actual msgid, which cannot be "undef". $obj->msgstr([INDEX, [STRING]]) With a STRING, a new translation will be set. Without STRING, a lookup will take place. When no plural is defined, use INDEX 0 $obj->plural([STRING]) Returns the actual msgid_plural, which can be "undef". $obj->references([STRING|LIST|ARRAY]) Returns an unsorted list of LOCATIONS. When options are specified, then those will be used to replace all currently defined references. Returns the unsorted LIST of references. $obj->removeReferencesTo(FILENAME) Remove all the references to the indicate FILENAME from the list. Returns the number of refs left. Parsing Log::Report::Lexicon::PO->fromText(STRING, [WHERE]) Parse the STRING into a new PO object. The WHERE string should explain the location of the STRING, to be used in error messages. $obj->toString(OPTIONS) Format the object into a multi-lined string. -Option --Default nr_plurals undef nr_plurals => INTEGER If the number of plurals is specified, then the plural translation list can be checked for the correct length. Otherwise, no smart behavior is attempted. $obj->unused The message-id has no references anymore and no translations. SEE ALSO
