Substitute and Substitute Into
The Substitute() function returns a copy of a string with a replacement expression. The Substitute Into() function changes the original string with a replacement expression.
For example, consider the following script:
str1 = str2 = "All things considered";
str3 = Substitute( str1, "All", "Some" );
// str3 holds the result of the Substitute, and str1 is not changed
str4 = Substitute Into( str2, "All", "Some" );
// Substitute Into returns nothing, so str4 is missing, and str2 is changed and now holds the result of Substitute Into
Show( str1, str2, str3, str4 );
This script returns the following output:
str1 = "All things considered";
str2 = "Some things considered";
str3 = "Some things considered";
str4 = .;
