information on connection zero.
Use the DELVAR command to delete MMS named variables.
The DELVAR command has the following syntax:
DELVAR <connection><remote_symbol>
The following table defines each part of the DELVAR command line.
This:
Is:
DELVAR
the command that requests the deletion of an MMS named variable.
You can abbreviate to three characters and use either upper or lower
case letters. Leave at least one space between each field in the
command line.
<connection>
the communication link between two applications. This is designated
by the connection identifier :C followed by an integer from 1 to 9999.
This must directly follow the DELVAR command, followed by the
remote symbol.
<remote_symbol>
the MMS variable name you are deleting. This must be in single
quotes and directly follow the connection identifier with no spaces
separating them.
Here are some examples of using the DELVAR command:
DELVAR :C88’TANK_TEMPERATURE’
DEL :C7’station_14’
To delete MMS named variable within the coprocessor itself, use
connection zero.
For example:
DELVAR :C0’MY_VARIABLE’
See the section titled Connection Zero, earlier in this chapter for more
information on connection zero.
