HP 53131A, 132A manual DMC string, arbitrary block Define Macro Command

Chapter 4 Command Reference

Introduction

*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.

Comments ∙ 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.
