Summary of SIZEDATA
NAME
sizedata - Data entry for sediment size statistics program
ABSTRACT
SIZEDATA allows for keyboard entry and modification of particle-size
analysis data and storage into a direct-access file for input to the
sedsize program.
METHOD
SIZEDATA allows the user to create a new file, add to an existing
file, modify data in an existing file, and list data to the screen
or store in a file. Particle-size distribution data entry is
facilitated by use of a table for picking a sequence or individual
particle diameters or phi values, and also allows particle diameters
to be entered individually. Additional data sets can be entered
using the same set of particle diameters or a new set.
HISTORY
Version 1.9 1997/06/02 - Fixed problem with end of file check on
read of direct access files.
Version 1.80 1995/08/11 - Code clean-up, prompts in mixed case
Version 1.4 1994/10/26 - Fortran version as ported to UNIX
workstations
1986 - first release - Fortran version for use on Prime computers
and a BASIC version for use on personal computers
DATA REQUIREMENTS
Size-distribution data are entered interactively. Each distribution
(data set) consists of a station description (up to 80 characters),
date of sample, time of sample, number of particle diameter sizes
(up to 33), the diameter sizes in millimeters, and the percent-finer
value for each size. Percent-finer values of 0 are ignored by the
program.
SYSTEM REQUIREMENTS
SIZEDATA is written in Fortran 77 with the following extension: use
of variable names longer than six characters. Generally, the
program is easily installed on most computer systems. The code has
been used on UNIX-based computers and DOS-based 386 or greater
computers having a math coprocessor and 1 mb of memory.
