# packxxk(1)

pack TI graphing calculator software files

## NAME

packxxk - pack TI graphing calculator software files

## SYNOPSIS

**packxxk** \[ **-t** *type* \] \[ **-d** *date* \] \[ **-o** *xxkfile* \] *appfile* ...

## DESCRIPTION

**packxxk** is a program to generate Flash Application and OS files for the Texas Instruments TI-73, TI-83 Plus, TI-84 Plus, TI-89, and TI-92 Plus graphing calculators.  The files generated are in the \`\`TIFL'' format used by recent versions of TI's GraphLink and TI-Connect software.

The input file to **packxxk** must be in TI-Hex or TIFL format to begin with, and (in order for the application to be installed) it must have been digitally signed before being packed.  **packxxk** does not do this, nor does it check for the presence of a signature.  You can use [**rabbitsign**(1)](/rabbitsign/1.md) to sign applications in several common formats.

If multiple input files are specified, **packxxk** creates a multi-part TIFL file.

### OPTIONS

- **-t** *type*

  Specify the type of program (e.g., \`8xk' for a TI-83 Plus application, or \`73u' for a TI-73 operating system.)  The default behavior is to infer the program type from the name of the input file.  (If the input file does not have a recognized suffix, the type is guessed based on the contents of the program header.)

- **-c** *id*

  Manually specify the calculator device ID (e.g., 0x73 for the TI-83 Plus, or 0x74 for the TI-73.)

- **-d** \[ *month*/*day*/*year* \| *day*-*month*-*year* \]

  Manually specify the date stamp for the application.  The default is to use the current date in the local time zone.

- **-o** *xxkfile*

  Specify the output file name (default is to write to standard output.)
