B.10 PL/I Implementations

Table B-10 lists the OpenVMS data types and their corresponding PL/I data type declarations.

2 DTYPE FIXED BINARY(7)
INITIAL((32)DSC$K_DTYPE_T),
2 CLASS FIXED BINARY(7)
INITIAL((32)DSC$K_CLASS_S),
2 CHAR_PTR POINTER; ¹

The length of the LENGTH field in each element of the array should correspond to the length of a string of characters pointed to by the CHAR_PTR field. The constants DSC$K_CLASS_S and DSC$K_DTYPE_T can be used by including the module $DSCDEF from PLI$STARLET.

access_mode FIXED BINARY(7)
(The constants for this type---PSL$C_KERNEL, PSL$C_EXEC, PSL$C_SUPER, PSL$C_USER---are declared in module $PSLDEF in PLI$STARLET.)

address POINTER

address_range (2) POINTER ¹

arg_list 1 ARG_LIST BASED,
2 ARGCOUNT FIXED BINARY(31),

POINTER; ¹

If the arguments are passed by value, you may need to change the type of the ARGUMENT field of the structure. Alternatively, you can use the POSINT, INT, or UNSPEC built-in functions and pseudovariables to access the data. X should be an expression with a value in the range 0 to 255 when the structure is allocated.

¹System routines are often written so the parameter passed occupies more storage than the object requires. For example, some system services have parameters that return a bit value as a longword. These variables must be declared BIT(32) ALIGNED (not BIT(n) ALIGNED) so that adjacent storage is not overwritten by return values or used incorrectly as input. (Longword parameters are always declared BIT(32) ALIGNED.)
²AST procedures and those passed as parameters of type ENTRY VALUE or ANY VALUE must be external procedures. This applies to all system routines that take procedure parameters.
³This is actually an unsigned integer. This declaration is interpreted as a signed number; use the POSINT function to determine the actual value.
⁵PL/I does not support FIXED BINARY numbers with precisions greater than 31. To use larger values, declare variables to be BIT variables of the appropriate size and use the POSINT and SUBSTR bits as necessary to access the values, or declare the item as a structure. The RTL routines LIB$ADDX and LIB$SUBX may be useful if you need to perform arithmetic on these types.
⁴System services require CHARACTER string representation for parameters. Most other system routines allow either CHARACTER or CHARACTER VARYING. For parameter declarations, n should be an asterisk (*).
⁶Routines declared in PLI$STARLET often use ANY, so you are free to declare the data structure in the most convenient way for the application. ANY may be necessary in some cases because PL/I does not allow parameter declarations for some data types used by OpenVMS. (In particular, PL/I parameters with arrays passed by reference cannot be declared to have nonconstant bounds.)
⁷For parameter declarations, the bounds must be constant for arrays passed by reference. For arrays passed by descriptor, *s should be used for the array extent instead. (OpenVMS system routines almost always take arrays by reference.)
⁸n is an expression that is evaluated at the time the structure is allocated. The value should be in the range 0-255.
++Alpha specific.

Note

All system services and many system constants and data structures are declared in PLI$STARLET.TLB.

While the current version of PL/I does not support unsigned fixed binary numbers or fixed binary numbers with a precision greater than 31, future versions may support these features. If PL/I is extended to support these types, declarations in PLISTARLET may change to use the new data types where appropriate.
