This chapter details the central LONGLIB graphics library routines.
A brief description of each routine is shown along with an example
of its call and a description of the associated parameters.
Parameters are shown in <> brackets are optional in systems permitting
optional parameters. They are are not accessed unless specifically
requested by other parameters values
.
The name of each parameter is followed by a letter indicating the variable type. Unless otherwise specified, integers are the default integer length of the machine (which is INTEGER*4 on the VAX).
I = INTEGER
R = REAL
C = CHARACTER
L = LOGICAL
Lengths are given in the standard plot units of inches. The routine FACTOR can be used to change the plot unit length. Angles are specified in degrees counter-clockwise from the x axis.
Unless specifically noted all parameters passed into a routine via the call statement will be used on a "read-only" basis, i.e., they will not be modified by the routine.
