channel (default "uart1:", see SETSTDIO statement). Otherwise, it will come
from the specified file or device. The execution will be held until the specified
number of characters has been received from the keyboard console, file or
communication channel. If a file does not contain the specified number of
characters, the execution will be resumed as soon as all available characters
in the file have been received.
