Interprets a compatibility mode BASIC/V program. BASIC/V is not part of the HP 3000 Series 900 Computer System Fundamental Operating Software and must be purchased separately.

Syntax

BASIC[ commandfile] [ ,[ inputfile] [ ,listfile] ]

Parameters

commandfile

Actual file designator of the source file or device from which BASIC/V commands and statements are input. This can be any ASCII input file. Formal file designator is BASCOM. Default is $STDINX.

inputfile

Actual file designator of the file containing data input for a BASIC/V program. This can be any ASCII input file. Formal file designator is BASIN. Default is $STDINX.

listfile

Actual file designator of the destination file for the program listing and output. This can be any ASCII output file. Formal file designator is BASLIST. Default is $STDLIST.

NOTE: The formal file designators used in this command (BASCOM, BASIN, and BASLIST) cannot be backreferenced as actual file designators in the command parameter list. For further information, refer to the "Implicit FILE Commands for Subsystems" discussion of the FILE command.

Operation Notes

The BASIC command is generally used for online programming in BASIC/V, but it can also be used to interpret BASIC/V programs submitted in batch mode. In batch mode, the BASIC/V >EOD command is required after any data following the BASIC/V >RUN command, or after the >RUN command itself if there is no data.

Use

This command may be issued from a session, job, or program. It may not be used in BREAK. Pressing Break suspends the execution of this command. Entering the RESUME command continues the execution.

Examples

To enter commands and data from your standard input device, with program listing and output transmitted to the standard output device, enter:

  BASIC

You may also submit commands and data to the BASIC/V interpreter through input files that you have stored on disk. Files created using the editor must be kept with the UNN (unnumbered) option of the editor KEEP command. In this example, BASIC/V interpreter commands and statements are submitted from the command file MYCOMDS. The data that the program uses is stored in the input file MYDATA. The program listing and output are written to the file MYLIST.
