PowerBASIC has a few keywords that make parsing strings trivial: <code>PARSE</code>, <code>PARSE$</code>, and <code>PARSECOUNT</code>. (<code>PARSE$</code>, not shown here, is for extracting tokens one at a time, while <code>PARSE</code> extracts all tokens at once into an array. <code>PARSECOUNT</code> returns the number of tokens found.)

Line 1,110 ⟶ 1,242:
This example uses the ''strtok()'' function to separate the tokens. This function is destructive (replacing token separators with '\0'), so we have to make a copy of the string (using ''strdup()'') before tokenizing. ''strdup()'' is not part of [[ANSI C]], but is available on most platforms. It can easily be implemented with a combination of ''strlen()'', ''malloc()'', and ''strcpy()''.
<
#include<stdio.h>
#include<stdlib.h>
Line 1,131 ⟶ 1,263:
return 0;
}</
Another way to accomplish the task without the built-in string functions is to temporarily modify the separator character. This method does not need any additional memory, but requires the input string to be writeable.

Hello.How.Are.You.Today</
<tt>splitstring</tt> and <tt>joinstring</tt> also work with longer "delimiters":
<
"Hello","How","Are","You","Today"</
But, of course, this could be solved with simple string replacement:
<
Hello.How.Are.You.Today</
The task asks us to ''Separate the string "Hello,How,Are,You,Today" by commas into an array (or list) so that each element of it stores a different word.'' but for many purposes the original string is an adequate data structure. Note also that given a string, a list of "word start" indices and "word length" integers can be logically equivalent to having an "array of words" -- and, depending on implementation details may be a superior or inferior choice to some other representation. But, in current definition of this task, the concept of "word length" plays no useful role.
Line 1,819 ⟶ 2,063:
Note also that J provides several built-in concepts of parsing: split on leading delimiter, split on trailing delimiter, split J language words. Also, it's sometimes more efficient to append to a string than to prepend to it. So a common practice for parsing on an embedded delimiter is to append a copy of the delimiter to the string and then use the appended result:
<
Here '''fn''' is applied to each ',' delimited substring and the results are assembled into an array.
Or, factoring out the names:
<

Line 1,835 ⟶ 2,079:
{{works with|Java|1.8+}}
<
System.out.println(String.join(".", toTokenize.split(",")));</
{{works with|Java|1.4+}}
<
String words[] = toTokenize.split(",");//splits on one comma, multiple commas yield multiple splits
Line 1,845 ⟶ 2,089:
for(int i=0; i<words.length; i++) {
System.out.print(words[i] + ".");
}</
The other way is to use StringTokenizer. It will skip any empty tokens. So if two commas are given in line, there will be an empty string in the array given by the split function, but no empty string with the StringTokenizer object. This method takes more code to use, but allows you to get tokens incrementally instead of all at once.
{{works with|Java|1.0+}}

StringTokenizer tokenizer = new StringTokenizer(toTokenize, ",");
while(tokenizer.hasMoreTokens()) {
System.out.print(tokenizer.nextToken() + ".");

a vector (i.e. array) of strings rather than a list of strings.
<
;;; print the vector
strings =>
** {'Hello' 'How' 'Are' 'You' 'Today'}</
It is also possible to give sys_parse_string a 'conversion' procedure, which is applied to each of the tokens.
E.g. it could be used to produce a vector of numbers, using the conversion procedure 'strnumber', which converts a string to a number:
<
{% sys_parse_string('100 101 102 103 99.9 99.999', strnumber) %} -> numbers;
;;; the result is a vector containing integers and floats,
;;; which can be printed thus:
numbers =>
** {100 101 102 103 99.9 99.999}</
Using lower level pop-11 facilities to tokenise the string:
<
lvars str='Hello,How,Are,You,Today';
;;; Iterate over string
Line 2,819 ⟶ 3,192:
endif;
;;; Reverse the list
rev(ls) -> ls;</
Since the task requires to use array we convert list to array
<
destlist(ls);
;;; Build a vector from them
Line 2,831 ⟶ 3,204:
printf(ar(i), '%s.');
endfor;
printf('\n');</
We could use list directly for printing:
<
printf(i, '%s.');

so the conversion to vector is purely to satisfy task formulation.

This will suffice to split a string into an array of substrings. It is used like this:

Generating a list form a string by splitting on a comma:
<
Joining the elements of a list by a period:

Thus the whole thing would look like this:
<
If you'd like to retain the list in a variable with the name "words", it would only be marginally more complex:

(In general, the <tt>regexp</tt> command is also used in Tcl for tokenization of strings, but this example does not need that level of complexity.)
