PIC 9(n)

Specifies the one-relative ordinal position of the actual argument in the USING phrase of the CALL statement used to call the subprogram that calls C$DARG. The value zero obtains the description of the actual argument in the GIVING phrase of that CALL statement. If the value specified is less than zero or greater than the number of actual arguments passed, an argument-description for an omitted argument will be returned (argumentType = 32). The actual number of arguments passed can be obtained with the C$NARG library routine. The actual number of arguments may exceed the number of formal arguments declared in the Procedure Division header of the program that calls C$DARG. All of the actual arguments can be accessed using C$DARG even though there is no formal argument name available for accessing the actual arguments beyond the number of formal arguments.

Group item

Receives the information about the data item.

 

Returns a number indicating the type of the argument data item.

 

Returns the BYTE-LENGTH of the argument data item.

 

Returns the number of digits defined in the PICTURE character-string for an argument that is a numeric or numeric edited data item as indicated by the argumentType field value; otherwise, the value zero is returned for nonnumeric data items. The digit count for a numeric or numeric edited data item does not include any positions defined by the PICTURE symbol P, which represents a scaling position.

 

Returns the position of the implied or actual decimal point for an argument that is a numeric or numeric edited data item as indicated by the argumentType field value; otherwise, the value zero is returned for nonnumeric data items. If the PICTURE symbol P was used in the description of the data item, the absolute value of the argumentScale value will exceed the argumentDigitCount value; in this case, a positive scale value indicates an integer with P scaling positions on the right of the PICTURE character-string and a negative scale value indicates a fraction with P scaling positions on the left of the PICTURE character-string.
