The ereplace() function searches a string expression for the search string and then, if at the start occurrence, replaces search.str with replacement.str for the amount of occurrences specified in occurrences.
Syntax
|
ereplace(str.exp, search.str, replacement.str {,occurrences {,start}}) |
Synonym(s)
|
change() swap() |
Parameter(s)
|
str.exp |
String in which the specified search.str is searched for. |
|
search.str |
String to search for in str.exp. |
|
replacement.str |
String to replace the specified search.str. |
|
occurrences |
Specifies the number of occurrences of search.str to be replaced by replacement.str. If not specified, defaults to 0, which replaces all found occurrences. |
|
start |
Specifies which occurrence of search string the replacement begins. If not specified, defaults to 1. |
Description
|
NOTE |
To use ereplace(), it is necessary to use a nondefault compiler compatibility option. Inserting the $options ext statement at the beginning of the program accomplishes this. |
Example(s)
Assigns the value "The old time" to nstring.
|
$options ext nstring = ereplace("The new time","new","old") |
This outputs "++-". The ereplace() function replaces one occurrence of "-" starting at the second occurrence.
|
print ereplace("---","-","+",2,1) |
