*DMC <string>, <arbitrary block>

(Define Macro Command)

*DMC <string>, <arbitrary block>

This command assigns a sequence of zero or more commands/queries to a macro

label. The sequence is executed when the label is received as a command or query.

The <string> parameter specifies the macro label. The macro label may not be a

common command/query header. It may be the same as an instrument-specific

command/query header; in this case, provided macros are enabled, the macro

expansion is executed and the instrument-specific command/query may be

executed by disabling macros.

The <arbitrary block> contains the sequence of commands/queries being labeled.

Parameters may be passed to the sequence during execution. Placeholders for

parameters appear in the sequence as a dollar sign followed by a single digit in the

range one to nine inclusive. The first parameter following the macro label is

substituted for the parameter placeholder labeled $1, and so on up to nine

parameters.

See the section titled “How to Program the Counter to Define Macros” in Chapter

3 of this guide.

• The maximum macro label length is 12 characters.

• Redefining an existing macro causes an execution error.

• The Counter allows up to four levels of recursion.

• There is no query form. Use *GMC? (see page 4-129) to query the current

definition of a macro label.
