Substring of a longstring using word counts
Note: Many $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for $Lstr_SubWord is Words. Or, you may find the features of the StringTokenizer to be more helpful.
This function takes a string or longstring input and produces a substring of the input using word counts.
The $Lstr_SubWord function accepts four arsguments and returns a longstring result.
Syntax
%result = $Lstr_SubWord(longstring, start, [words], [delim])
Syntax terms
| %result | A substring of the input longstring. |
|---|---|
| longstring | An arbitrary string or longstring. This is a required argument |
| start | A number between 1 and 2**31-1 that indicates the starting word number in the input string. This is a required argument. |
| words | A number between 1 and 2**31-1 that indicates the length in words of the result string. This is an optional argument and defaults to the number of words left in the string. |
| delim | A string containing from 1 to 255 characters which are the delimiters for the longstring. This is an optional argument and defaults to a blank. |
Usage notes
- Leading and trailing delimiters are removed from the resulting string, but all delimiters within the boundaries of the result are preserved.
Examples
- To set
%restoa time:%res = $Lstr_SubWord('Once upon a time you dressed so fine', 3, 2)
- To set
%restoupon a:%res = $Lstr_SubWord('Once upon a time you dressed so fine', 3, 2, ' n')
