If Statement

The If Statement module allows you to create a condition on which the enclosed modules will get executed or not. This is similar to the conditional statements seen in the VBScript and other scripting languages. Using the interface you can compare RoboRealm variables against other variables or values to determine if the following modules should be executed or not.

Instructions

1. Variable - Specify the variable to test using the dropdown menus. Select [new] to create a new variable that is not already in the list.

2. Comparison - Select the appropriate comparison.

equals - true if the variable and value are equal.

not equals - true if the variable and value are not equal

greater than - true if the variable is greater than the value. For numbers this is a direct comparison, for text the order is alphabetical.

greater or equal to - true if the variable is greater than or equal to the value.

less than - true if the variable is less than the value. For numbers this is a direct comparison, for text the order is alphabetical.

less or equal to - true if the variable is less than or equal to the value.

contains - true for text comparisons where the variable has the specified value as a sub component (i.e. word) within in. For example, "The dog jumped over the fence" contains "dog".

does not contain - true if for text comparisons where the variable does NOT contain the specified value. For example, "The dog jumped over the fence" does NOT contain "cat".

is within - true for text comparisons where the variable is within (present in) the value. For example, "dog" is within "The dog jumped over the fence". This is logically the opposite of the "contains" comparison.

is not within - true for text comparisons where the variable is NOT within (absent from) the value. For example, "cat" is not within "The dog jumped over the fence". This is logically the opposite of the "does not contain" comparison.

starts with - true for text comparisons where the variable starts with the specified value. For example, "The dog jumped over the fence" starts with "The dog".

not starts with - true for text comparisons where the variable does not start with the specified value. For example, "The dog jumped over the fence" does not start with "The cat".

ends with - true for text comparisons where the variable ends with the specified value. For example, "The dog jumped over the fence" ends with "fence".

not ends with - true for text comparisons where the variable does not end with the specified value. For example, "The dog jumped over the fence" does not end with "wall".

is null - true if the variable either contains zero (for numbers) or an empty string "" for text.

is not null - true if the variable either contains a non-zero value or has some text even if a single letter.

is a multiple of - true for numeric comparisons where the variable is a multiple of the specified value (aka modulus). For example, 4 is a multiple of 2 since 4 mod 2 or 4 % 2 is zero.

is not a multiple of - true for numeric comparisons where the variable is not a multiple of the specified value (aka modulus). For example, 5 is not a multiple of 2 since 5 mod 2 or 5 % 2 is 1.

3. Type - Select the comparison type. The comparison type helps specify how the comparison is performed. For example, if two strings "100" and "2" are compared as text "2" will be greater than "100", but if compared as integers then "100" will be greater than "2".

4. Value - Specify the value to compare to. For variables use the dropdown list. For other static values such as numbers or strings simply type in the value. You can also use the expressions in the value field to test variables based on mathematical expressions of other variables/numbers.

5. Join - Specify the type of join to perform on multiple conditions

6. Latch - Select the Latch Condition if you only want the If Statement to trigger when the condition transitions from false to true, i.e. once true, the condition will not trigger until the condition evaluates to false and then true again.
