reverse a string

Former Member — Thu, 14 Jul 2005 08:32:47 GMT

Hi all,

Is there any function to reverse a string ? I also want to know whether there is any function that takes a string as input and returns nth word of that string.

regards,

Vishnu Priya.

Hello Vishnu Priya,

To find the nth word of the string, use STRLEN statement.

To reverse a string, use the function module STRING_REVERSE.

Hi Priya,

Thanks for ur very quick reply. STRLEN will return the length of a string. But I want to find nth word in a string. For Eg. if string is ' This is a sample string'. I want to get 4th word in that string, i.e, 'sample'. Is there any such function. I will try STRING_REVERSE. Thank u.

regards,

Vishnu Priya

one way is to use an internal table for the string.....

to get the nth word, split your string into an internal table and then read the nth entry of the table..

split str at ' ' into table itab.

now suppose for 4th word,

read table itab index 4.

this will give you the 4th word in the string...

if u dont want to use an internal table then u can also use explicit variables for splitting...

split str at ' ' into f1 f2....fn.

and then use the respective result field

Things are always easier than people imagined. Just a hint for getting nth word of a string:

data: chr type sychar01,

str type string,

nth type i value 5,

len type i value 1.

chr = str+nth(len).

write: / chr.

See what will happen.
