Roper Photometric manual Following parameters are illegal, Multiple Parameter Functions

Single Parameter Some functions require a single parameter. Fractional/decimal and negative Functions values are not allowed. Numeric expressions generate an error. Whitespace can

be included anywhere inside the parentheses.

The following parameters are legal:

loop_begin(	50	);
loop_begin(	50	/ *exposure count*/	);
loop_begin(	50
);

The following parameters are illegal:

loop_begin	( 50 );	whitespace before parentheses
loop_begin( 50, );		contains a	comma
loop_begin( 50 0 );		two numeric entries, only one allowed
loop_begin( -50 );		minus sign	is illegal
loop_begin(	(5*10));	numeric expressions not allowed

Multiple Parameter Functions

A few functions require multiple parameters. There are no variable argument lists, so each parameter is always required. The parameters must be separated by commas. Insert whitespace as desired.

The following examples are legal:

pixel_readout(0,	100,	1,	50,	2 );
pixel_readout(	0,	100,	1,	50,	2 );
pixel_readout(			/****MAIN FUNCTION****/
	0,		/* serial offset of “0” */
	100,		/* serial size, value:100 */
	1,		/* serial binning */
			/* parallel size */

50,	/*par bin*/.
2);

Verbs A verb describes which function is performed next. Verb names are a mixture of lowercase text and underscore characters. All verbs are followed by parentheses, even if the verb does not require parameters. There is no whitespace between the verb name and the opening parenthesis. List parameters inside the parentheses and separate the parameters with commas. Whitespace is allowed in the parameter list, but is not required. After the closing parenthesis, add a semicolon. See sample below:

verb1();

verb2(parameter, parameter, parameter); verb3(parameter); verb4(parameter); (whitespace) verb5();

You can use several verbs on a single line, one verb per line, several lines of whitespace, or any combination of the above.
