Arguments and Syntax
The syntax of an AcroBASIC command shows you all the
components necessary to use it. Commands can contain required
and optional arguments. They also contain a number of symbols:
• Braces { }—arguments that are optional. Do not type the
braces in your code.
• Parentheses ( )—arguments that are optional, and must
appear within the parentheses in your code. Also used to
indicate variables and expressions. If replacing a constant with
a variable or parametric equation, use parentheses to
“contain” the variable/equation. Signed (-) or (+) constants
must be in parentheses.
• Commas (,)—delimiters between arguments in specific
commands. In addition, select commands use commas to
control spacing and line feeds. To understand the separator’s
specific use in a command, refer to the command’s format
and description.
• Semicolons (;)—delimiters between arguments in specific
commands. In addition, select commands use semicolons to
control spacing and line feeds. To understand the separator’s
specific use in a command, refer to the command’s format
and description.
• Slash mark (/)—signifies an incremental move in select
commands.
• Quotes (“ ”)—arguments within the quotes must appear within
quotes in your code.
• Number sign (#)—device arguments following number signs
must include the number sign in your code.
• Ellipsis (…)—arguments can be given for multiple axes
The following examples illustrate how to interpret common syntax:
Example 1
ACC {rate}
In the ACC command, the lower case word rate is an argument.
Arguments act as placeholders for data you provide. If an argument
appears in braces or parentheses, the argument is optional.
For example, the following sets the acceleration ramp to 10,000 units
per second
2
.
ACC 10000
When you issue a command without an optional argument, the
controller reports back the current setting. Not all commands report
back, and some require you to specify an axis. For example, the
following reports the current acceleration rate in program 0.
P00>ACC
10000
