Efficient looping over strings

[Former Member]

ABAPers,

I need to loop over all the characters in a string. Here is the pseudo code:

data: myData TYPE string.
data: n TYPE i.
data: ch TYPE char1.

n = STRLEN( myData).
DO n TIMES.
  ch = myData(sy-index).
  ...
ENDDO.

While this code would work, the problem is that I am actually iterating over myData two times. STRLEN itself is internally iterating over myData to compute the length.

Is there a more efficient looping mechanism without going through STRLEN?

Thank you in advance for your help.

Hi,

You can try this when it comes to converting things

WHILE myData IS NOT INITIAL.

do something

ENDIF.

myData = myData+1(*).
