HP 4155A Programmer's Guide

Using HP Instrument BASIC
Creating ASP-like IBASIC Programs
Programming Tips
This section describes features and tips of IBASIC programs in relation to
ASP programs. Some examples use an example measurement setup le
named \VTH.MES". Before executing these examples, you need to save setup
data to a le named \VTH.MES" on the diskette.For an example setup, see
\Example Application Setup for Vth Measurement" in Chapter 3.
File Name Variables.
You can specify a string variable for the le name in
NNNNNNNNNNNNNNNNNNNNNNNNNN
SAVEDATA as follows:
Filename$="DATA1.DAT"
EXECUTE ("SAVEDATA Filename$")
This feature allows you to create a more simple program as follows
.
Example ASP Program Following ASP program gets a setup le, makes measurements, and saves
results to following les: VTH1 , VTH2 , ... VTH10 . Program is 21 lines.
1 GET P VTH
2 SINGLE
3 SAVE D VTH1
4 SINGLE
5 SAVE D VTH2
6 SINGLE
7 SAVE D VTH3
.
.
.
21 SAVE D VTH10
Corresponding IBASIC
Program.
The following HP Instrument BASIC (IBASIC) program does the same
operation as the above ASP program. The program is simplied by using a
lename variable Filename$ and the FOR NEXT keyword.
10 EXECUTE ("GETSETUP 'VTH.PRO'")
20 FOR I=1 TO 10
30 EXECUTE ("SINGLE")
40 Filename$="VTH"&VAL$(I)&".DAT"
50 EXECUTE ("SAVEDATA Filename$")
60 NEXT I
In line 40, the Filename$ is dened. For example, Filename$ = "VTH1.DAT"
when I =1. So, the 21-line ASP program can be converted to a 6-line IBASIC
program.
