string_func - charlen, dbmaxlen, numofchar, strlen

These length functions have an unnamed character-like argument.

Syntax

... func( arg ) ...

Effect

The following table shows the length functions with an unnamed argument. The arguments arg of all length functions except dbmaxlen are character-like expression positions. The argument of dbmaxlen is a character-like functional operand position. The return value has the type i for all length functions.

Function func Return Value
charlen Length of the first character of arg in the code page used: 1 for a single Unicode character; 2 for surrogate pairs.
dbmaxlen Maximum length of a string defined in the ABAP Dictionary (RAWSTRING, SSTRING, STRING, or GEOM_EWKB). If the string is unrestricted, the constant abap_max_db_string_ln or abap_max_db_rawstring_ln from the type pool ABAP is returned. The latter is also returned for the built-in ABAP types string and xstring.
numofchar Number of characters in arg, where trailing blanks are not counted in data objects with fixed lengths or in data objects with the type string.
strlen Number of characters in arg, where trailing blanks in data objects with fixed lengths are not counted, whereas in data objects with the type string they are.
