This appendix describes:
HP Fortran recognizes certain logical names at compile time and run time.
A logical name specified must not contain brackets, semicolons, or periods. The system treats any name containing these punctuation marks as a file specification, not as a logical name.
To view the previously set logical names, use the SHOW LOGICAL command (see HELP SHOW LOGICAL):
$ SHOW LOGICAL PROJ_DIR %SHOW-S-NOTRAN, no translation for logical name PROJ_DIR |
Use a DEFINE command to set (define) a logical name:
$ DEFINE logical-name equivalence-value |
For example, to associate the process logical name PROJ_DIR with the directory DISK2:[PROJ], type a DEFINE command:
$ DEFINE PROJ_DIR DISK2:[PROJ] $ SHOW LOGICAL PROJ_DIR "PROJ_DIR" = "DISK2:[PROJ]" (LNM$PROCESS_TABLE) |
To use logical name tables other than the process table, specify qualifiers to the DEFINE (or ASSIGN) command. A system manager can define logical names system-wide, perhaps in a system startup procedure.
To remove the association of a logical name and its value, use the DEASSIGN command:
$ DEASSIGN logical-name |
Table D-1 describes the logical names that HP Fortran recognizes at compile time.
| Logical Name | Description |
|---|---|
| FORT$LIBRARY |
Specifies a default text library to be searched for included library
modules (INCLUDE statements that specify library modules) that are not
explicitly specified.
FORT$LIBRARY is recognized by both Compaq Fortran 77 and HP Fortran. For more information, see Section 2.2.4. |
| FORT$INCLUDE | Specifies an additional directory to be searched for included source files (INCLUDE statements that specify files). For more information, see Section 2.3.25. |
Table D-2 describes the logical names HP Fortran recognizes at run time.
| Logical Name | Description |
|---|---|
| FOR nnn | Allows the user to specify the directory and file name at run time for a logical unit ( nnn) for which the OPEN statement does not specify a file name (leading zeros are required). If the appropriate logical name is not set and the OPEN statement does not specify a file name for that logical unit, a default file name of FOR nnn.DAT is used. For more information, see Section 6.6.1. |
| FOR$READ | Specifies the name of a file to receive input from a READ statement instead of SYS$INPUT. For more information, see Section 6.6.1. |
| FOR$ACCEPT | Specifies the name of a file instead of SYS$INPUT to receive input from an ACCEPT statement. For more information, see Section 6.6.1. |
| FOR$PRINT | Specifies the name of a file instead of SYS$OUTPUT to receive output from a PRINT statement. For more information, see Section 6.6.1. |
| FOR$TYPE | Specifies the name of a file instead of SYS$OUTPUT to receive output from a TYPE statement. For more information, see Section 6.6.1. |
| FOR$CONVERT nnn | For an unformatted file, specifies the nonnative numeric format of the data at run time for a logical unit ( nnn). Otherwise, the nonnative numeric format of the unformatted data must be specified at compile time by using the FORTRAN command /CONVERT qualifier. For more information, see Chapter 9. |
|
FOR$CONVERT.
ext
and FOR$CONVERT_ ext |
For an unformatted file, specifies the nonnative numeric format of the data at run time for a file whose suffix is ext. Otherwise, the nonnative numeric format of the unformatted data must be specified at compile time by using the FORTRAN command /CONVERT qualifier. For more information, see Chapter 9. |
Table E-1 lists the library modules contained in the HP Fortran system library FORSYSDEF.TLB, a text library.
The library modules consist of definitions, in Fortran source code, of related groups of system symbols that can be used in calling OpenVMS system services. FORSYSDEF also contains library modules that define the condition symbols and the entry points for Run-Time Library procedures.
Each new version of the operating system may add new FORSYSDEF library modules to the text library FORSYSDEF. To determine whether a particular library module is installed on your system, use the LIBRARY/LIST command.
For example, the following command sequence searches for the library module named $SMGDEF:
$ LIBRARY/LIST/ONLY=$SMGDEF SYS$LIBRARY:FORSYSDEF.TLB |
