$SubErs

Remove occurrence of one string from another

Note: Most Sirius $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.
