Introduction to HPGETPROC-PLABEL
The HPGETPROCPLABEL intrinsic dynamically loads an XL procedure and
returns the procedure's label (plabel) to your program.
You can use the plabel to make a dynamic call to the procedure if the
programming language contains features for making dynamic procedure
calls, for example, the CALL procedure in HP Pascal/XL. Refer to the HP
Pascal Reference Manual (31502-90001) for details on the CALL procedure.
The syntax of HPGETPROCPLABEL is as follows:
HPGETPROCPLABEL(procname,plabel,status,firstfile,casesensitive)
HPGETPROCPLABEL searches through a list of XLs (referred to as the
binding sequence, described below) to locate the procedure you specify in
the procname parameter. When the procedure is found, it is dynamically
loaded and its plabel is returned to your program in the plabel
parameter.
Appendix B contains a program example illustrating the use of the
HPGETPROCPLABEL intrinsic.
The status parameter returns status information about the intrinsic call,
in the following manner:
Bits (0:16) | When the signed integer value
| represented by these bits is zero,
| a normal status is indicated. A
| negative value indicates an error
| condition, and a positive value
| indicates a warning condition.
Bits (16:16) | The signed integer value
| represented by these bits defines
| the subsystem that set the status
| information in Bits (0:16). The NM
| loader identification number is
| 104. When the value represented by
| these bits is zero, a normal status
| is indicated.
