The
.echo
directive causes the specified message to be written to the standard
output stream,
stdout
. The end of the message is marked by the newline
character; therefore, no comment field is permitted with this directive. This
directive can be used for both informational and diagnostic purposes.
Example
.echo The end of the data section is {data_end}.x
The symbol data_end is a user-defined label, which has been defined prior to the
directive in this example. If the value of the label is 0x42f8, then this directive
produces the following message:
The end of the data section is 42f8
