Printing the Current Value

You can send the PRINT command followed by a parameter or bit

whose value you want to see. Bits return the following values:

• -1 when set.

• 0 when clear.

You can use a question mark in place of the PRINT command. The

question mark is a shortcut in a terminal emulator.

NOTE: When printing a system parameter, the value returned is

either an integer or a 32-bit floating point.

When printing a user parameter (P0-P4095), the value returned is

either an integer or 64-bit floating point.

Example

The following demonstrates how to view values stored in parameters

and bits. Parameter 6144 provides the current encoder position;

Bit24 provides the current state of input 24.

PRINT P6144

PRINT Bit24

?P6144

?Bit24

A Word on Aliases

Parameters and bits can use aliases. You only need to assign the

alias once, and then can use it throughout user programs. The alias

lets you provide a name that makes sense for programs, and makes

programs easier to read.
