The Data Acquisition Pac provides several new BASIC keywords for your HP-71. You can use these
keywords in a BASIC program to control the operation of the HP 3421A Data Acquisition/Control Unit,
or you can use the programs provided by the pac, which also use these keywords. Thus, these keywords
form the basis of the Data Acquisition Pac. Each of the keywords performs a function that would
normally take several BASIC statements. Thus, the keywords make programming easier, and speed up the
response of a control program.
NOTE
Many of the keywords communicate directly with the HP 3421A Data
Acquisition/Control Unit (to obtain readings or send commands). When
executed, such keywords automatically clear flag -23 in the HP-71. (The
flag is left clear when the keyword completes execution.)
3.1 SYNTAX CONVENTIONS
When you use BASIC keywords, you must use proper syntax in order for the computer to understand their
meaning. The following syntax guidelines are used throughout this section:
DOT MATRIX TYFE Words in dot matrix type may be keyed in using either lowercase
or uppercase letters, but otherwise must be entered exactly as
shown. Commands, statements and functions entered in lowercase
are converted internally to uppercase.
italics type Items in italics are the parameters you supply, such as a filename.
tern Filenames and other character strings can be enclosed with single
or double quotation marks and can be entered in lowercase or
uppercase letters. Quoted filenames are converted to uppercase
internally.
[] Square brackets enclose optional items.
| If items are separated with a vertical bar, you may choose one or
the other of the items, but not both.
{} Braces indicate that an item is required. Usually, the braces are
used in conjunction with the vertical bar to indicate that one of a
series of items is required. For example, { OM | OFF } indicates
that either OH or OFF must be selected.
