Chapter 6, IBASIC Controller
PROGram Subsystem
Example setting the value of a simple variable
OUTPUT 714;"PROGram:SELected:NUMBer Variable,15"
or
OUTPUT 714;"PROG:NUMB Variable,15"
Example setting the value of a one dimensional array [Array(5)] with 6 elements
OUTPUT 714;"PROGram:SELected:NUMBer Array,0,1,2,3,4,5"
or
OUTPUT 714;"PROG:NUMB Array,0,1,2,3,4,5"
NOTE: Individual array elements cannot be set with the :NUMBer command.
Example setting the value of a two dimensional array [Array(1,2)] with 6 elements
OUTPUT 714;"PROGram:SELected:NUMBer Array,0,1,2,3,4,5"
or
OUTPUT 714;"PROG:NUMB Array,0,1,2,3,4,5"
Arrays are filled by varying the right-most dimension the fastest. After executing the above
statement the array values would be, Array(0,0)=0, Array(0,1)=1, Array(0,2)=2,
Array(1,0)=3, Array(1,1)=4, Array(1,2)=5.
NOTE: Individual array elements cannot be set with the :NUMBer command.
:NUMber? <varname>
The :NUMBer? query command is used to return, to an
external controller, the current value of numeric variables or arrays in an IBASIC
program in the Test Set . <varname> is the name of an existing numeric variable
or array in the IBASIC program, and can be sent as either character data (name
not enclosed in quotes) or string data (name enclosed in quotes).
NOTE: If the variable name <var_name> is longer than 12 characters it must be sent as string data
(<var_name> enclosed in quotes). For example, OUTPUT 714;"PROG:NUMB
’Var_name’".
Attempting to send a <var_name> longer than 12 characters as character data
(<var_name> not enclosed in quotes) will generate the following error:
HP-IB Error: -112 Program mnemonic too long
For simple variables the value is returned as a series of ASCII characters
representing a numeric value in scientific notation (+3.00000000000E+000). For
arrays the values are returned as a comma separated list of ASCII characters
representing a numeric value in scientific notation. For example,
+3.00000000000E+000,+3.00000000000E+000,+3.00000000000E+000, etc.
Array values are sent by varying the rightmost dimension of the array the fastest.
