	[Move] VE4 DI10 OT01 GO OT10		Example of “Hosted” Mode
	Program
	In the program [Move], the maximum move velocity is set to 4, the command
	incremental distance is set to 10, output 1 and output 2 are turned off and on
	simultaneously, axis one then moves 10 units. After axis one stops moving, output
	1 is turned on and output 2 is turned off. These changes of outputs 1 and 2 occur
	at the same time.
	The flow of the program is controlled with WT (wait for an event or condition to
	occur), TD (wait for a pre–set amount of time to elapse), and IF (if a certain
	condition is true at this instant, then execute a block of commands) statements.
	External controllers such as PLC and computers can be coordinated by the digital
	outputs and ASCII serial commands. The commands that can be entered from the
	keypad and used in a program are listed in Table 6-1.
Variables	Memory space allows for up to 100 variables. All variables are stored as fixed
	point numbers. All variables are global. All standard variables are volatile, though
	non–volatile variables are available as well. Variables can be used in many parts
	of the program, such as:
	S	Arithmetic
	S	Conditional Expressions
	S	Loop Counts
	S	Distance and velocity commands
	S	Set values
	S	Set command values or parameters
	S	Set analog signals
	S	Read analog or temperature input
	S	Display information such as position or velocity
	S	Any place that a number can be used, a variable can be used

Variable Names

Descriptive variable names can be assigned, instead of V1, V2, etc. Variable names can be up to 14 characters, but the first 10 characters must be unique. A name can contain other printable ASCII characters, such as numbers, underscores, exclamation points, even spaces. Upper and lower case characters are supported within variable names, and these variable names are case sensitive. ASCII control characters such as LF and CR are not supported. All variables must be enclosed in parentheses, (variable name). Parentheses are not legal variable characters.
