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

  1. To set %res to a time:

    %res = $Lstr_SubWord('Once upon a time you dressed so fine', 3, 2)

  2. To set %res to upon a:

    %res = $Lstr_SubWord('Once upon a time you dressed so fine', 3, 2, ' n')
