STRUPCASE

STRUPCASE

Tip: See also the IDL_String::ToUpper method, which provides similar functionality but with an object-oriented interface.

The STRUPCASE function returns a copy of String converted to upper case. Only lowercase characters are modified—uppercase and non-alphabetic characters are copied without change.

Examples


To print an uppercase version of the string “IDL is fun”, enter:

PRINT, STRUPCASE('IDL is fun')

IDL prints:

IDL IS FUN

Syntax


Result = STRUPCASE(String)

Return Value


Returns a string composed of uppercase characters.

Arguments


String

The string to be converted. If this argument is not a string, it is converted using IDL’s default formatting rules. If it is an array, the result is an array with the same structure where each element contains an uppercase copy of the corresponding element of String.

Keywords


None.
