WHILE ... DO ... WEND    loop structure 
The WHILE ... DO ... WEND construct is a conditional loop construct which allows the conditional execution of one 
or more program lines according to the result of a test carried out at the beginning of the loop.  16 loops can be nested.

XOFF    define XOFF character 
The XOFF command is used in a number of ways to control software handshaking during data transfer. 
 
There are 4 variations: 
XOFF#[port] 
When used on its own, XOFF halts data transmission from the specified serial port.  This provides a way to control the 
output data stream which otherwise can only be controlled via the CTS line.  XON is used to re-enable...

XON    define XON character 
The XON command is used in a number of ways to control software handshaking during data transfer. 
 
There are three variations: 
XON #[port] 
When used on its own, XON re-enables data transmission after it has been halted using XOFF.  If no port is specified, the 
default port as defined by OPORT is assumed. 
 
Note that CLEAR OUTPUT and ESCAPE will also re-...

YEAR    read/set year value 
YEAR is used to read or set the year value on the internal clock/calendar. 
 
When reading it returns an integer from 0 to 99. 
 
When setting, the year number from 0 to 99 must be specified. 
 
An incorrect value will leave the current setting unchanged. 
Examples: 
YEAR=89
PRINT YEAR
Syntax: 
YEAR = [integer 0..99]
[num-var] = YEAR

 Error Messages 
The ARGUS can generate about 100 different error messages. 
 
The associated text can be requested via the REPORT ERN command. 
 
The number of the last error message can be obtained via ERN; and the line which caused this error with ERL. 
 
Almost all error messages can be trapped and handled with ON ERROR, except: 
 
 - NMI/STOP 
 
 - STOP 
 
 - Out of memory 
 
 - Error in...
