Terminal I/O Statements
Added October 2024
Terminal/keyboard input and output is actually just a variation of Sequential File I/O (e.g. INPUT, PRINT, ...) with the only difference being that the terminal channel is always 0. For terminal output statements, the channel parameter is optional; omitting it is the same as specifying a channel value of zero. For terminal input, the channel parameter must be omitted and optionally replaced by a prompt. For example:
map1 name$,s,20
input "What's your name? ", name$ ! (channel replaced by prompt)
print #0, "hello"; name$ ! (explicit channel 0)
print "Goodbye" ! (implicit channel 0)
See Sequential File I/O for further details.
