Strip Function

Format

s = strip(string_expression);

Description

The strip function removes trailing whitespace (blanks, newlines, etc.) from the string_expression. The result of the function is often used as an argument to other functions such as the length and concat functions.

You will generally not have to use the strip function when working with variable-length strings since they do not have spaces automatically added to the end of the text to match a fixed width.

Return Value

The function returns a string with no trailing whitespace.

Example

PROC GLOBAL

alpha (30) firstName, lastName, fullName;

PROC EXAMPLE

firstName = "John";
lastName = "Henry";

fullName = concat(strip(firstName), " ", strip(lastName));
numeric nameLength = length(strip(fullName));

// fullName is "John Henry "
// nameLength is 10
