CONV dtype|#( … )
dtype = Type you want to convert to (显式转换)
# = compiler must use the context to decide the type to convert to (隐式转换)
*简单理解
DATA: LV_TEXT TYPE CHAR01,
LV_STR TYPE STRING.
" 显式转换：将LV_TEXT转换成STRING类型
LV_STR = CONV STRING( LV_TEXT ).
" 隐式转换：将LV_TEXT转换成LV_STR的类型
LV_STR = CONV #( LV_TEXT ).
