USGS Open-File Report 2005-1001: C Language Software

The following programs were written in "C" and compiled with DJGPP (version 2.01) to run on Windows 98 with the GNU operating system installed and run from the Born-Again-Shell (bash), which is run in a DOS-prompt window. The DJGPP is a 32-bit protected-mode development system available from Walnut Creek CD-ROM (ISBN 1-57176-228-0) that is suitable for porting Unix programs to DOS. GNU is a Unix-like operating environment distributed by the Free Software Foundation (ISBN 1-882114-57-4). The user must install the GNU package, and set their system to run in the bash environment before using these programs.

Software Code: Documentation files and source code are contained in the compressed file: c_code.tar. Right click this UNIX tar file and use "Save As" to download the software. This tar file, which puts it’s contents into a new directory called c_code, may be expanded in the bash shell with the command: tar xvf c_code.tar

Executable Programs: Compiled versions of the code and a "readme" file are contained in the compressed file: apsas_up.tar. Right click this tar file and use "Save As" to download the software. This tar file, which puts it’s contents into a new directory called apsas, may be expanded in the bash shell with the command: tar xvf apsas_up.tar. The programs may be operated from this directory or can be copied to any directory in the user’s path.

HTML and Word versions of the documentation for the C-language programs can be accessed through the links below.

PROGRAM	DOCUMENTATION
CLTRM - To manually enter 200 and/or 30 micron diameter tube electro-resistance multichannel particle-size analyzer (EMPSA) analyses via the keyboard.	HTML WORD
ENTRY - To enter sediment data as relative frequency percents at whole phi intervals.	HTML WORD
GSANV - To facilitate keyboard entry of navigation and descriptive information associated with raw sediment data processed during grain-size analysis.	HTML WORD
GSTAT - To retrieve sediment analyses and the corresponding identifiers from the sorted raw data files and compute standard textural parameters.	HTML WORD
GSTATM - To input frequency percent data entered by ENTRY and analyze as described in GSTAT.	HTML WORD
JSORT - To sort sediment analyses samples by lab number and retrieve complete sets which will be appended to the complete data set file.	HTML WORD
RSAM - To manually enter sand-fraction and gravel fraction data via the keyboard.	HTML WORD

Questions regarding installation and implementation of DJGPP or the GNU utilities should be directed to Walnut CD-ROM and the Free Software Foundation, respectively.
