String Manipulation in PeopleCode

Here are a few examples of string manipulation in PeopleCode. I will try to update this post with more examples if I think of more situations.


Number to String
This will convert a number variable to a string. This may be helpful with specific formatting or string concatenation.  For more details check out this entry in PeopleBooks.

Local number &Num = 2;

Local string &NumAsString = NumberToString("%03",&Num);

/* &NumAsString will now equal "002" */




Substring

This will take a substring of a larger string.

Local string &foo = "This is a foo string.";

Local string &start_key = "Th";

Local string &end_key = ".";




Local integer &start_pos = Find(&start_key, &foo) + Len(&start_key);

Local integer &end_pos = Find(&end_key, &foo);




Local string &result = Substring(&foo, &start_pos, &end_pos - &start_pos);

/* &result will now equal "is is a foo string" */
