Jul 24, 2023 · 1 min read · ABAP ·

In ABAP, you can manipulate strings using various string functions and methods. Here are some examples of how to perform common string operations like concatenation and length calculation:

Concatenation:

Using the CONCATENATE statement:

1CONCATENATE 'Hello' 'World' INTO lv_string.

Using the & operator:
```
1lv_string = 'Hello' & 'World'.
```

Length Calculation:
- Using the STRLEN function:
```
1DATA(lv_length) = STRLEN( lv_string ).
```

Substring Extraction:

Using the SUBSTRING function:

1DATA(lv_substring) = SUBSTRING( lv_string FROM 3 FOR 5 ).

String Replacement:

Using the REPLACE function:

1DATA(lv_new_string) = REPLACE( lv_string 'old' 'new' ).

Case Conversion:

Using the CONV method:

1DATA(lv_uppercase) = lv_string->CONV( |U| ).

Using the TRANSLATE function:

1DATA(lv_uppercase) = TRANSLATE( lv_string TO UPPER CASE ).

Padding:

Using the CONCATENATE statement:

1CONCATENATE lv_string ' ' INTO lv_padded_string.

Using the CONDENSE statement:
```
1CONDENSE lv_string.
```

These are just a few examples of string manipulation in ABAP. There are many more functions and methods available in the ABAP language for different string operations.
