Compiles and prepares 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

BASICPREP[ commandfile] [ ,[ progfile] [ ,listfile] ]

Parameters

commandfile

Actual file designator of the input file from which the BASIC/V compiler commands are read. This can be any ASCII file. Formal file designator is BSCTEXT. Default is $STDINX.

progfile

Actual file designator of the program file on which the prepared program segments are written. When progfile is omitted, the MPE segmenter creates the program file, which resides in the temporary file domain as $OLDPASS. To create your own program file, do so in one of two ways:

  • By using the BUILD command and specifying a file code of 1029 or PROG and a numextents value of 1. This file is then used by the PREP command.

  • By specifying a nonexistent file in the progfile parameter, in which case a temporary job file of the correct size and type is created.

listfile

Actual file designator of the file to which the listing is written. This can be any ASCII output file. Formal file designator is BSCLIST. Default is $STDLIST.

NOTE: The formal file designators used in this command (BSCTEXT and BSCLIST) 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 BASICPREP command compiles and prepares a program for execution from a " fastsave" file generated by the BASIC/V interpreter. If the progfile parameter is omitted, the prepared program segments are stored in the systemcdefined temporary file $OLDPASS. To save the prepared program in a file other than $OLDPASS, either create a file and specify its file name on the BASICPREP command line, or specify a nonexistent progfile.

A program compiled and prepared with the BASICPREP command may be executed with the MPE/iX RUN command.

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 compile and prepare a program named MYPROG from the BASIC/V fastsave file named MYCOMDS, with the listing directed to the standard list device, enter:

  BASICPREP,MYCOMDS

The file MYPROG is an ASCII file that contains the following BASIC/V compiler commands:

  $CONTROL USLINIT SOURCE
$COMPILE MYPROG
$EXIT

The above example initializes the USL and lists the program, compiles the fastsave program MYPROG, and then exits from the compiler.
