Saving Expressions to a File
If you construct a complicated expression or procedure, you can save them
for future use in Maple. If you save the expression or procedure in the Maple
internal format, Maple can retrieve it more efficiently than from a document.
Use the save command to write the expression to a .m file. For more inform-
ation on Maple internal file formats, refer to the ?file help page.
>
In this example, small expressions are used. In practice, Maple supports ex-
pressions with thousands of terms.
>
>
You can save these expressions to the file qbinom.m.
>
Clear the memory using the restart command and retrieve the expressions
using the read command.
