GPIB Command Statements

Enter

ENTER is the complement of OUTPUT and is used to transfer data from the addressed

instrument to the controller. The syntax is:

Figure 1-8. Enter Command Syntax

ENTER is nearly always used in conjunction with OUTPUT.

Some BASIC Examples

100 OUTPUT 719, "...programming codes..."

110 ENTER 719; "...response data..."

ENTER statements are commonly formatted, requiring the secondary command USING

and the appropriate image items. The most-used image items involve end-of-line (EOI)

suppression, binary inputs, and literal inputs. For example:

100 ENTER 719 USING "#, B"; A, B, C

suppresses the EOI sequence (#), and indicates that variables A, B, and C are to be filled

with binary (B) data. In another example:

100 ENTER 719 USING "#, 123A"; A$

suppresses EOI and indicates that string variable A$ is to be filled with 123 bytes of literal

data (123A).

NOTE Be careful when using byte-counting image specifiers. If the requested

number of bytes does not match the actual number available, data might be

lost or the program might enter an endless wait state.
