Remove occurrence of one string from another

Note: Many $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $SubErs function is the Remove function.

This function removes an occurrence of one string from another.

The $SubErs function accepts four arguments and returns a string result that is part of the first argument string.

Syntax

%string = $SubErs(string, substring, start_pos, [count])

Syntax terms

%string The part of the string argument that remains after substring is removed from it.
string An arbitrary string.
substring Another arbitrary string.
start_pos A starting position within string.
count A repeat count indicating the number of occurrences of substring to be removed. This is an optional argument, and it defaults to 1.

Examples

  1. This statement sets %JUNK to CDABAB:

    %JUNK = $SubErs('ABCDABAB', 'AB')

  2. This statement sets %JUNK to WE WAITED LONG ENOUGH:

    %JUNK = $SubErs('WE HAVE WAITED LONG ENOUGH', 'HAVE ')

  3. This statement sets %JUNK to WE HAVE AITED LONG ENOUGH:

    %JUNK = $SubErs('WE HAVE WAITED LONG ENOUGH', 'W', 5)

  4. This statement sets %JUNK to E HAVE AITED LONG ENOUGH:

    %JUNK = $SubErs('WE HAVE WAITED LONG ENOUGH', 'W', 1, 5)
