Each program requires certain arguments specific to its operation. These are explained in the manual pages and in the usage messages. Most programs are ``case-sensitive''; almost all options must start with an upper-case letter. We have tried to choose letters of the alphabet which stand for the argument so that they will be easy to remember. Each argument specification begins with a hyphen (except input file names; see below), followed by a letter, and sometimes a number or character string immediately after the letter. Do not space between the hyphen, letter, and number or string. Do space between options. Example:
pscoast -R0/20/0/20 -Ggray -JM6i -Wthin -B5 -V -P 
map.ps
