Direct Assignment Through Programming

This assignment method applies to l ocal, common, system, and PAL

parameters. You can perform direct assignment in main, macro, or MDI

program s. Direct assignment is done by setting the parameter equal to

some value in an equation using the “ = ” operator. For example, to assign

a value of 2 to parameter number 100, simply enter the following program

block:

#100=2;

The value to the left of the equals sign must contain the # sign followed by

a legal parameter number. This parameter number can also take on the

form of:

#parameter expression = parameter expression

Example 20.14

Legal Parameter Numbers

#6=1;

#144=1;

#[14/2]=1;

#[#6]=1;

In Example 20.14, all of the parameter numbers are legal. Any time you

use a different parameter between the [] symbols, the current

value of that

parameter is evaluated. For example:

#1=4;

#1=#1+2;

The net result of the above two blocks would be the assignment of a value

of 6 to parameter #1.

Example 20.15 illustrates the assignment of values to t he parameters.

Example 20.15

Assigning Values to Parameters

#100=1+1;

#100=5-3;

#100=#3;

#100=#7+1;

#100=#100+1;

You can also assign multiple paramacro parameters in a single block. In a

multiple assignment block, each assignment is separated by a comma. For

example:

#1=10,#100=ROUND[#2+#3],#500=10.0*5;

1 2 ... 681 682 683 684 685 686 687 688 689 690 691 ... 819 820
