BASIC Language
USR Function
Example:
Remarks:
In the form <y$> = TIME$, TIME$ returns an eight character string in the
form: hh:mm:ss. If <x$> is not a valid string, an error message will be dis-
played.
Purpose:
Format:
Example:
Remarks:
If <number> is omitted, the default value is zero.
If the W parameter in the USR statement is not specified, the watchdog timer
refresh will be performed as usual. If the W parameter is specified, then the
user must include a watchdog timer refresh routine in the assembly program.
The watchdog timer prevents the program from overrunning. When the set
time has run out, the ASCII Unit is reset, and the message “I/O ERR” is dis-
played on the programming console of the PC.
By refreshing the watchdog timer before its set value is up, the program can
be continuously executed.
To refresh the watchdog timer in the assembly program, execute the follow-
ing two steps every 90 milliseconds:
AIM #DF,03
OIM #20,03
The following table lists the Argument type and its corresponding Accumula-
tor code number.
Index register X contains the memory address where the argument is stored.
The address differs depending on the type of the argument as shown in the
following diagram.

Accumulator Value
<y$> is a string variable to which the current value of the time is
to be assigned.
TIME$ = “09:10:00”
PRINT TIME$
To call a user-written assembly language program.
USR [<number>](<argument>)[,W]
<number> is a digit from 1 to 9 that was previously assigned to
the given assembly program with the DEF USR statement.
<x> is an argument used to pass data from the BASIC program
to the assembly program.
J = USR2(I),W
hh:mm: sets the hours and minutes (seconds 00)
hh:mm:ss: sets the hours, minutes, and seconds
