1.Before using A$ on the 9825 is necessary to enter ”dimA$[6]” to allocate a string variable. This statement allows six characters.

2.In the HP9816 system, variables cannot be created from the keyboard; they must be created by running a program. (See error 910 for that system.) To get around this, type in a very short program as follows:

SCRATCH		(Hit “EXEC” key)
10	A = 0	(Hit “ENTER” key)
20	A$ = ‘’’’	(Hit “ENTER” key)
30	END	(Hit “ENTER” key)

(Hit “RUN” Key)

This program creates the variables ‘A’ and ‘A$’ so that they may be accessed in immediate mode and changed at will. This program is not necessary for the HP-85 Calculator.

3-60. EXAMPLE PROGRAMS

Several example programs for the 8842A using various controllers are presented in the remaining figures in this section. In all of these examples, the 8842A is set to IEEE-488 address 4 (rear panel switch setting 000100). Of course, any other address (00 to 30) could be substituted.

In each of these examples, the instrument is cleared prior to configuration set-ups. This ensures that the 8842A configuration has been completely defined.

To run these programs, it is not necessary to type in all the comments (which appear to the right of the exclamation marks). Also, spaces are placed between commands for ease of reading; they are not required.
