The file.readline function only allows one argument and can only read the next
line. The above should produce an error message.

It means "true". The middle portion of the for is an expression and tor loop
continues while the expression is not 0 (or ""). Since, "1" in this case does
mean the for will continue for ever.
Another way to read a file is
fh = file.open("c:/xxx.txt","r")
for each li index lineNum in fh
do stuff with li
endfor
