Hello everyone, I'm using Stu.StrTrimEndA. But the non-blank character is deleted if the number of it is one. Do you have any idea? My code is following: VAR sBufferOneChar: STRING := 'A '; sBufferTwoChar: STRING := 'AA '; END_VAR //NG (sBufferOneChar: 'A ' --> '') Stu.StrTrimEndA(pString:= ADR(sBufferOneChar)); //OK (sBufferTwoChar: 'AA ' --> 'AA') Stu.StrTrimEndA(pString:= ADR(sBufferTwoChar));
