HP-41: LIF to ASCII read/write

lifasread – a Ruby script to read an ascii file stored in a lif-formated file (used by the HP-41 as file format on mass storage mediums. Tested on Linux. Run the script with the -h (or –help) option to see how it is used.

lifaswrite – a Ruby script to write a text file to a lif-formated file (the reverse of “lifasread”. Run the script with the -h (or –help) option to see how it is used.

NAME
lifasread - LIF ascii file read

SYNOPSIS
lifasread [-hv] [--help, --version] [lif-file] [destination file]

DESCRIPTION
lifasread is used as a tool for HP-41 or HP-71 connected to a PC. lifasread reads an ascii file inside a lif formated file. It reads only the first ascii file and so the lif-file should be consisting of only one file. To create a lif file with only one file from an HP-41, have your calculator hooked to the PC and/or a lif-writing mass storage device and XEQ "NEWM 001". Then put the size of the ascii file in the X register and its name in the Alpha register. Then XEQ "CRFLAS". Fill it with content as needed, and XEQ "SAVEAS" to save the file to mass storage. Then from your PC execute lifasread to extract the content. The sister-script "lifaswrite" will reverse the process.

-v, --version

EXAMPLE
lifasread hdrive1.lif textfile.txt

This would extract the ascii file from "hdrive1.lif" and write it to the file "textfile.txt".

NAME
lifaswrite - LIF ascii file write

SYNOPSIS
lifaswrite [-hv] [--help, --version] [text file] [destination lif-file]

DESCRIPTION
lifaswrite is used as a tool for HP-41 or HP-71 connected to a PC. lifaswrite takes text file and writes an ascii file inside a lif formated file. It creates a lif-file of 32KB with only one ascii file in it. The name of that ascii file is the first line in the text file. To read the file into your HP-41, you make sure the lif-file resides on the a mass storage device accessible from the calculator and then XEQ "GETAS". The ascii file will then be loaded into Extended Memory. The sister-script "lifasread" will read an ascii file from within a lif-file.

EXAMPLE
lifasread textfile.txt hdrive1.lif

This would create the lif-file "hdrive1.lif" with the content of "textfile.txt" as an ascii file within the lif-file.
