Your file reference may also contain command interpreter variables and
expressions that are evaluated before the file reference is parsed and
validated. In the following file equation, the exclamation point (!)
instructs MPE/iX to substitute the variable name MYFILE with the
actual file designator assigned to that variable by the SETVAR
command.
SETVAR MYFILE,'FILE2.MYGROUP.MYACCT'
FILE FILE1=!MYFILE
|
The HPFOPEN and FOPEN intrinsics also allow you to embed
command interpreter variables and expressions in the file reference.
The following file references are valid when passed as formal
designators:
!MYFILE
!MYFILE.!HPGROUP.!HPACCT
!FILE1/![FINFO(-!FILE1",33)]
|
For more information about using command interpreter variables and
expressions, refer to the Command Interpreter Access and
Variables Programmers' Guide (32650-90011).
