a meaningful and attractive layout, and
a maximum information in the least amount of space.
These goals are implemented as completely as possible. In situations where they are incompatible, economic use of space takes priority. However, there are a number of LIST command options that may be used to change or improve the appearance of the output when that is more important than conserving space. LIST requires only the command itself and the name of the file to be listed:
LIST File1 $
TEXTWRITER uses the P-STAT Programming Language (PPL) instructions PUT and PUTL to specify the strings, values and expressions. Additional PPL may be included to test values and output appropriate strings. Thus, if Gender equals "M", the string "Mr." is written, but if Gender equals "F", "Ms." is output. Control words format the text and position it in specific columns and lines.
Special features include the use of labels files to supply character string replacement for integer values and PostScript controls to supply font information. Information such as the current date and time can be included by using P-STAT system variables in the PUT statements.
Desired plots and options are specified at the subcommand level. Reasonable settings for output parameters are automatically selected by the PLOT command but may be reset by the user.
PostScript support provides camera ready plots whenever there is a PostScript printer available. It is independent of the types of computer or operating system. Plots can be approximated first in character format with the PostScript information added when the test plot is satisfactory. If there is a PostScript previewer (for example, ghostscript) available, the PostScript output can be viewed on the screen before it is printed. Most of the PLOT subcommands are available in both modes; character and PostScript.
One feature that is only available when PLOT is used with PostScript controls is the ability to have multiple plots on a page. In addition these plots can be combined on a page with TEXTWRITER BOXPLOT, and SURVEY command output.
The BOXPLOT subcommand in EDA constructs all of the plots using Tukey's formulas for hinges, outliers, and whiskers. The BOXPLOT command permits a choice of method. The assumed method is TUKEY (also called the STANDARD method). The alternate method is based on percentiles. The choice of method determines the defaults for the printing of outliers and whiskers.
