Galil DMC-13X8 Displaying Variables and Arrays, Using the MG Command to Configure Terminals

The Final Value is 99999.99

The message command normally sends a carriage return and line feed following the statement. The carriage return and the line feed may be suppressed by sending {N} at the end of the statement. This is useful when a text string needs to surround a numeric value.

Example:

#A

JG 50000;BGX;ASX

MG "The Speed is", _TVX {F5.1} {N} MG "counts/sec"

EN

When #A is executed, the above example will appear on the screen as: The speed is 50000 counts/sec

Using the MG Command to Configure Terminals

The MG command can be used to configure a terminal. Any ASCII character can be sent by using the format {^n} where n is any integer between 1 and 255.

Example:

MG {^07} {^255}

sends the ASCII characters represented by 7 and 255 to the bus.

Summary of Message Functions:

FUNCTION	DESCRIPTION
" "	Surrounds text string
{Fn.m}	Formats numeric values in decimal n digits to the right of the decimal point
	and m digits to the left
{$n.m}	Formats numeric values in hexadecimal
{^n}	Sends ASCII character specified by integer n
{N}	Suppresses carriage return/line feed
{Sn}	Sends the first n characters of a string variable, where n is 1 thru 6.

Displaying Variables and Arrays

Variables and arrays may be sent to the screen using the format, variable= or array[x]=. For example, V1= , returns the value of V1.

Example - Printing a Variable and an Array element

#DISPLAY	Label
DM POSX[7]	Define Array POSX with 7 entries
PR 1000	Position Command
BGX	Begin
AMX	After Motion
V1=_TPX	Assign Variable V1
POSX[1]=_TPX	Assign the first entry
V1=	Print V1
