INPUT$

Field of Application

Function returning a string of data, limited in regard of number

of characters, from the standard IN channel, or optionally from an

OPENed ﬁ le or device.

Syntax INPUT$(<nexp

>[,<nexp

>])

<nexp

> is the number of characters to be read.

<nexp

> optionally speciﬁ es a ﬁ le or device using the number assigned

to it when it was OPENed.

Remarks

If no ﬁ le or device is speciﬁ ed, the input will come from the standard I/O

channel (default "uart1:", see SETSTDIO statement). Otherwise, it will

come from the speciﬁ ed ﬁ le or device. The execution will be held until the

speciﬁ ed number of characters has been received from the keyboard console,

ﬁ le, or communication channel. If a ﬁ le does not contain the speciﬁ ed

number of characters, the execution will be resumed as soon as all available

characters in the ﬁ le have been received.

The maximum number of characters that can be returned using an INPUT$

statement is 65,536 characters.

Examples

This example reads a sequence of 25 characters from the printer’s built-in

keyboard and assigns them to a string variable named Z$:

. . . . .

1000 OPEN "CONSOLE:" FOR INPUT AS #1

1010 Z$=INPUT$(25,1)

. . . . .

In this example, 10 characters are read from the standard IN channel

and assigned to a variable.

10 A$=INPUT$(10)

1 2 ... 127 128 129 130 131 132 133 134 135 136 137 ... 331 332
