STRLEN
Tip: See also the IDL_String::Strlen method, which provides similar functionality but with an object-oriented interface.
The STRLEN function returns the length of its string-type argument. If the argument is not a string, it is first converted to string type.
Examples
To find the length of the string “IDL is fun” and print the result, enter:
PRINT, STRLEN('IDL is fun')
IDL prints:
10
Syntax
Result = STRLEN(Expression)
Return Value
Returns the string length.
Arguments
Expression
The expression for which the string length is desired. If this parameter is not a string, it is converted using IDL’s default formatting rules in order to determine the length. The result is a long integer. If Expression is an array, the result is a long integer array with the same structure, where each element contains the length of the corresponding Expression element.
