The procedure lprint returns NULL and prints its arguments in a one-dimensional format.

The expressions expr1, expr2, ..., each separated from the others by a comma and a space, are printed on a single line.

Like most procedures in Maple, the arguments to lprint are evaluated before being passed to the procedure.

In general, the printed form produced by lprint is valid Maple input.

Maple will print all expressions after normal evaluation using lprint if the interface variable prettyprint is set to $0$.

Because lprint displays output as a side effect, and returns NULL as the procedure value, the ditto commands, %, %%, and %%%, will not recall the output from lprint.

The procedure lprint is intended for device independent printing and makes no use of special features of the user interface. For pretty-printing, using a two-dimensional output format, see print. For formatted output, see printf and fprintf.

Calling lprint[2] instead of lprint produces line-broken and indented output for procedures, but the same output as lprint for all other expressions.

The lprint command is thread-safe as of Maple 15.

For more information on thread safety, see index/threadsafe.

The lprint[2] command is new in Maple 2021.
