NAME
|
|
scan - scan standard input for possible assignment to variables
|
|
|
|
SYNOPSIS
|
|
scan(x_1, x_2, ..., x_n)
|
|
|
|
TYPES
|
|
x_1, x_2, ... any
|
|

return integer

|
DESCRIPTION
|
|
When input is from a terminal, execution is halted and input is read
|
|
until a newline is entered. Strings of non-whitespace characters
|
|
are evaluated in succession and if the corresponding x_i is an lvalue,
|
|
the resulting value is assigned to x_i. If the number of strings
|
|
read exceeds n, only the first n strings are evaluated. If the number
|
|
of strings is less than n, the later x_i are ignored.

EXAMPLE
|
|
> global a, b, c, d;
|
|
> scan(a, 0, c, d)
|
|
> 2+3 b=a^2 3+4i 3+"a"
|
|
> print a,b,c,d
|
|
