Checking whether a String only containes numbers

Hi,

I have a string. This can sometimes contain only numbers. Is there and method to check whether the staring is a number?

Thanks

Hello Lilan

Simple code:

* String contains only digits
  IF ( string CO '0123456789' ).  " or CO '01234567890 ' including space

  ELSE.

  ENDIF.

Regards

Uwe

try this demo code -

data l_text type string.

data d1 type i.

data d2 like sy-abcde.

l_text = '12'.

d2 = sy-abcde.

translate d2 to lower case.

if l_text CA sy-ABCDE or

l_text CA d2.

write 'char'.

else.

write ' num'.

endif.

Hi Lilan.

Just follow the foll steps :

1. Declare var1 type d

oref type ref to cx_root.

2. Write the foll code(assuming str is your string )

try.

d = s / 2.

catch cx_sy_conversion_no_number into oref.

endtry.

3. If oref is initial, the string is a number

Else the string has some alphabets.
