progress-4gl Strings Converting upper and lower case
Example
As mentioned before strings are normally case insensitive but that only regards comparison of strings. There's built in functions for changing case.
CAPS (string)
Makes string upper case
LC(string)
Makes string lower case
DEFINE VARIABLE c AS CHARACTER NO-UNDO.
DEFINE VARIABLE d AS CHARACTER NO-UNDO.
c = "Hello".
d = "World".
DISPLAY CAPS(c) LC(d). // HELLO world
Remember strings normally are case insensitive
DEFINE VARIABLE c AS CHARACTER NO-UNDO.
DEFINE VARIABLE d AS CHARACTER NO-UNDO.
c = "hello".
d = "hello".
DISPLAY CAPS(c) = LC(d). // yes
Unless specificed as CASE-SENSITIVE
DEFINE VARIABLE c AS CHARACTER NO-UNDO CASE-SENSITIVE.
DEFINE VARIABLE d AS CHARACTER NO-UNDO.
c = "hello".
d = "hello".
DISPLAY CAPS(c) = LC(d). // no
