print(e1,
e2, ... )
e1,
e2, ... - any expressions
·
The function print displays the values of the expressions
appearing as arguments, and returns NULL as the function value. The expressions
printed are separated by a comma and a blank. Note that print('``') will print a
blank line. The ditto commands, % and %%, will not recall the output of the
print command, since the return value of the function is NULL.
·
The following Iris variables control the format. See interface
for setting Iris variables.
·
The Iris variable prettyprint is checked to determine the format
in which the expressions are to be printed. If set to true (the default value)
the expressions will be displayed in a two-dimensional format, centered if
possible. If set to false the expressions will be line printed in one dimension.
·
The Iris variable verboseproc is checked to determine how the body
of Maple procedures (i.e. the code) will be displayed. It can be displayed in
full, with indentation, or abbreviated to simply ``...''. By default user
procedures are displayed in full, and Maple library procedures are abbreviated.
·
The Iris variable screenwidth specifies the number of characters
that fit on the output device being used. Since most CRTs are 80 characters
wide, the default value is 79.
·
The Iris variable labelling (or labeling) enables the use of %
variables to reduce the size of the output. These % labels identify common
subexpressions (those appearing more than once) in the output.
·
The evaluation of arrays, tables, procedures, and operators is
different from other objects in that when assigned to a name, they will normally
print with simply the name. For example, if the name A has been assigned
array([1,2,3]) then A; will display just A. To print the array object in full
use print(A);
·
There is a limited facility for user-defined formatting of
functions. For example, if the user assigns
`print/complex` := proc(real,imag) real + 'j'*imag end
then during output of the value complex(2,3), the `print/complex`
procedure will be called with the arguments 2, 3 resulting in the value 2 + 3*j
which will finally be displayed as 2 + 3 j. Note that arguments are formatted
first, and alias substitutions take place after formatting is completed.
