The CTRFLD function centers a character string within a field. The number of leading spaces is equal to or one less than the number of trailing spaces.
CTRFLD is useful for centering the contents of a field and its report column, or a heading that consists only of an embedded field. HEADING CENTER centers each field value including trailing spaces. To center the field value without the trailing spaces, first center the value within the field using CTRFLD.
