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
- 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)
