$SubErs

Remove occurrence of one string from another

Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $SubErs function is the Remove (String 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.

The first argument is an arbitrary string.

The second argument is another arbitrary string.

The third argument is a starting position in the first argument string.

The fourth argument is a repeat count indicating the number of occurrences to be removed. This is an optional argument and defaults to 1.

Syntax

<section begin="syntax" />%STRING = $SubErs(string, substring, start_pos, count) <section end="syntax" />

%STRING is part of the first argument string.

For example, this statement sets %JUNK to CDABAB:

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

This statement sets %JUNK to WE WAITED LONG ENOUGH:

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

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

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

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

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