Chapter 6, IBASIC Controller
PROGram Subsystem
For simple string variables the value is returned as a quoted string (“This is an
example.”). For string arrays the values are returned as a comma separated list of
quoted strings (“This is an example.”,“This is an example.”). The string array
elements are returned in ascending order (Array$(0), Array$(1), Array$(2), etc.).
If an attempt is made to query the value of a string variable or array and no
IBASIC program is in the Test Set an
IBASIC Error: -283 Illegal
variable name
is generated. If an attempt is made to query the value of a string
variable or array and the string variable specified in <varname> does not exist in
the program an
IBASIC Error: -283 Illegal variable name
is
generated.
Syntax
PROGram[:SELected]:STRing? <varname>
NOTE:
The program commands and syntax used to enter string data from the Test Set into the
external controller will depend upon the programming language used in the external
controller. The examples which follow represent the capabilities of HP
