Given a function declared with #!F-adobe-times-medium-i-normal--18* n #!EF input formal parameters, the first #!F-adobe-times-medium-i-normal--18* n #!EF values supplied in the function call are assigned to the first #!F-adobe-times-medium-i-normal--18* n #!EF formal parameters. If you supply #!F-adobe-times-medium-i-normal--18* i < n #!EF values in the function call, then only the first #!F-adobe-times-medium-i-normal--18* i #!EF of the function's formal parameters are assigned the supplied values. #!N #!N The missing arguments are assigned the value of #!F-adobe-times-bold-r-normal--18* NULL #!EF . #!N #!N #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lall539,dxall540 h By-Name Arguments #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
