STRUPCASE Function

result = STRUPCASE(string)

string The string to be converted.

If not of type string, string is converted to string using the default formatting rules of PV-WAVE. (These rules are described in Free Format Output in Chapter 8 of the PV-WAVE Programmer's Guide.)

result A copy of string converted to uppercase letters. If string is an array, the result is an array with the same structure, with each element containing the substring of the corresponding string element.

None.

Only lowercase characters are modified by STRUPCASE; uppercase and nonalphabetic characters are copied without change.

This example uses STRUPCASE to convert lowercase characters to uppercase in several different strings.

a = 'A StRInG oF miXeD caSE'
PRINT, STRUPCASE(a)

A STRING OF MIXED CASE

; Create a string with a mix of uppercase and lowercase characters.

; Convert the string in a to uppercase and display the result.

b = 45
INFO, STRUPCASE(b)

Expression           STRING    = '      45'

; Create an integer scalar variable. Examine the result of

; STRUPCASE applied to b. Note that b is converted to a string.

c = STRARR(3)

; Create a three-element string vector.

c(0) = 'StrInG 0'
c(1) = 'sTrINg 1'
c(2) = 'StrinG 2'

; Assign a string with a mix of uppercase and lowercase characters

; to each element of c.

PRINT, TRANSPOSE(STRUPCASE(c))

STRING 0
STRING 1
STRING 2

; Display the vector of strings of c after converting it to uppercase.

; Use TRANSPOSE to view the vector as a column.
