problem detecting uppercase

[juanluis_ragel]

hi,

I'm beginner.

I have a stupid question :-). Paste my Example:

DATA: lowletters(28) TYPE c VALUE 'abcdefghijklmnñopqrstuvwxyz',

string(100) TYPE c VALUE 'WORDINUPPERCASE'.

IF string CA lowletters.

WRITE 'string is lower-case'.

ELSE.

WRITE 'string is upper-case'.

ENDIF.

Result of report:

string is lower-case

Why??? I don't understand. I read help a lot of time about CA (Contains Any) and it say: "c1 contains at least one character from the string c2. ". In my Example c1 (string) NOT CONTAINS at least one character from the string lowletters. Maybe Im crazy.

Can you help me?

A lot of thanks in advance.

Best regards.

hi Juan,

CA is case sensitive...

Contains any (ca)

If ‘SAP’ ca ‘ABAP/4’.
			Write:/ ‘True’.
		Else.
			Write:/ ‘False’.
		Endif.
				True

this code of yours is working in this way ..

DATA: lowletters(28) TYPE c VALUE 'abcdefghijklmnnopqrstuvwxyz',
string(100) TYPE c VALUE 'WORDINUPPERCASE'.
 
IF string CA 'abcdefghijklmnnopqrstuvwxyz'.
WRITE 'string is lower-case'.
ELSE.
WRITE 'string is upper-case'.
ENDIF.

try this

REPORT ABC line-size 255.

DATA: lowletters(28) TYPE c VALUE 'abcdefghijklmnñopqrstuvwxyz',
string(100) TYPE c VALUE 'WORDINUPPERCASE'.

IF string CA 'abcdefghijklmnñopqrstuvwxyz'.
WRITE 'string is lower-case'.
ELSE.
WRITE 'string is upper-case'.
ENDIF.

declare lowletters of length 27(exact length) , its working

REPORT ABC line-size 255.

DATA: lowletters(27) TYPE c VALUE 'abcdefghijklmnñopqrstuvwxyz',
string(100) TYPE c VALUE 'WORDINUPPERCASE'.

IF string CA lowletters.
WRITE 'string is lower-case'.
ELSE.
WRITE 'string is upper-case'.
ENDIF.

WOW!

a lot of thanks!!!

exact length problem! Now it's works.

But i think that i'll never understand why.

May be because if you dont give the exact length , the extra character will be taken as space ,

so both the variables will contain space

so the SY_SUBRC will be 0 as both contain spaces

[Former Member]

The reason is due trailing SPACE at the end. Also, you can use CONDENSE statmenet with NO-GAP to delete the trailing spaces in the string.

Hi,

But it doesn't work if we have a variable which is the type c, and we want to get only the num data:

for example, I have :

parameters: pa(10) type c.

if pa CA 'abcdefghijklmnopqrstuvwxyz'.

WRITE / 'pa is the type num'.

endif.

even if the parameters pa has type c, I want to verify the input data in this field and get only the numeric value.

may be in string comparision the checking is case INsensitive.
