Example Output

`*****************************************************************************`
`**************************    GCmdT() example   *****************************`
`*****************************************************************************`
GCmdT() will return a trimmed response of GCommand()
The command 'PR ?,?' will return the relative position of the A and B axes
<<PR ?,? with GCommand():  0, 10000
:>>
<<PR ?,? with GCmdT():  0, 10000>>
 
 
`*****************************************************************************`
`**************************    GCmdI() example   *****************************`
`*****************************************************************************`
GCmdI() will return the value of GCommand() parsed as an int
The command 'MG _LMS' will return the available space in the vector buffer of the S plane.
MG _LMS with GCmdT():  511.0000
MG _LMS with GCmdI(): 511
 
 
`*****************************************************************************`
`**************************    GCmd() example   ******************************`
`*****************************************************************************`
GCmd() will execute the given command but does not return a value.
GCmd is useful for basic operations such as beginning motion or setting speed
GCmd(g, "BG A");
GCmd(g, "SP 5000");
 
 
`*****************************************************************************`
`**************************    GCmdD() example   *****************************`
`*****************************************************************************`
GCmdD() will return the value of GCommand parsed as a double
The command 'MG @AN[1]' will return the value of Analog Input 1
MG @AN[1] with GCmdD(): 9.7726
 
 
`*****************************************************************************`
`************************    Galil Double Format   ***************************`
`*****************************************************************************`
Galil Controllers expect double values to be formatted to 4 decimal places
Unformatted double value: 0.00235
Formatted double value rounded to 4 decimal places: 0.0024
