String Variables
The output of the instrument may be numeric or character data depending
on what is queried. Refer to the specific commands for the formats and types
of data returned from queries.
Express String Variables Using Exact Syntax
In HP BASIC 5.0, string variables are case sensitive and must be expressed
exactly the same each time they are used.
Address Varies According to Configuration
For the example programs in the help file, assume that the device being
programmed is at device address 707. The actual address varies according to
how you configured the bus for your own application.
The following example shows the data being returned to a string variable:
10 DIM Rang$[30]
20 OUTPUT 707;":ANALOG1:RANGE?"
30 ENTER 707;Rang$
40 PRINT Rang$
50 END
After running this program, the controller displays:
+8.00000E-01
