Program File Management

A program file is a file that contains an HP Business BASIC/XL program.

The program is stored in a file in one of the following formats:

BASIC SAVE A binary program file that contains a correct HP

Business BASIC/XL program. It can be stored and

retrieved more efficiently than an ASCII or BASIC DATA

file. It does not have to be converted to ASCII or

BASIC DATA format when it is stored, or have the syntax

checked when it is retrieved. A program is to be

compiled must be stored in this form.

_______________________________________________________

NOTE "Clean" BASIC SAVE files from time to time by

saving the program in that file to an ASCII file

from the interpreter, using GET to bring the ASCII

file into the interpreter and then using RESAVE to

store the file to the BASIC SAVE file. This is

necessary because the interpreter does not do

complete "garbage collection" when program lines

are deleted or modified.

_______________________________________________________

ASCII An ASCII program file has fixed-length 80-byte records.

Each program line is a series of one or more records.

If a line exceeds the record length, the record ends

with a continuation character (&) and the line continues

in the next record. An ASCII file looks like the output

of the LIST;NONAME command.
