Finding digits in variable

[Former Member]

Hello, I have a question. I have one variable called lv_tst. i have declared it like this:

lv_tst(3) TYPE C,

Now, sometimes this variable may have only one digit like 1 through 9 and other times it may have 10. What I am looking to do is when

lv_tst has a single digit then i want to

Concatenate '00' to lv_tst into another variable.

but when lv_tst has 2 digits such as 10 or 11 or anything uptil 99 then:

Concatenate '0' to lv_tst into another variable.

but i don't know what is the syntax to find our how many digits have occupied in lv_tst.

Please help.

Thanks.

Hi Venkat,

try this:

l_i = strlen( lv_tst ).

Hello Venkat,

Please use the FM CONVERSION_EXIT_ALPHA_INPUT to add leading zeros.

data : lv_tst(3).
 
 lv_tst = '2'.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'
   EXPORTING
     INPUT         = lv_tst
  IMPORTING
    OUTPUT        = lv_tst

Write lv_tst.

O/P : 002.

Thanks

hi venkat,

There are Function module for your scnerio

data: lv_t TYPE char3.

lv_t = 1.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

   EXPORTING

     input         = lv_t

  IMPORTING

    OUTPUT        = lv_t

           .

WRITE lv_t.

lv_t = 13.

CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

   EXPORTING

     input         = lv_t

  IMPORTING

    OUTPUT        = lv_t

           .

WRITE lv_t.
