Working with Macros

FXDeko User’s Guide

OMMENTS

A comment is text within a macro that does not affect the function of the macro.

Comments make macros easier to analyze and edit, especially if the macro was
written some time ago or written by another programmer. Many programmers
consider a program incomplete without comments. You may find the same to be
true of your macros.

A single-line comment starts with a pound sign (#). FXDeko ignores text to the
right of the pound sign.

# This comment is on a line by itself.

command # This one shares a line with a command.

Another way to create a comment is to precede the comment with /* and close it
with */. FXDeko ignores text between /* and */. This way, you can create
multiple-line comments.

/* This is a multiple-line comment.

None of this text affects the function

of this macro; FXDeko ignores

every line of it */

OOPS

Conditional commands instruct FXDeko to execute specific commands only
under certain circumstances. FXDeko supports the conditional commands if,

else

and elseif.

The if command includes a test expression, which evaluates to zero (false) or
non-zero (true). A list of one or more commands, then an end command, follows
the if command:

if expression=

# commands

end

If the expression is true, FXDeko executes the commands between if and end.

The if command is often used with the else command:

if expression=

# commands

else

# commands

end

If the expression is true, FXDeko executes the commands between if and

else

; otherwise, the commands between else and end are executed.

You can introduce more conditional actions by nesting conditions…
