- The components of such relational expressions can be [comparisons](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abencomparison_glosry.htm) or [predicates](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenpredicate_glosry.htm). Note that for [comparison expressions](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abencomparison_expression_glosry.htm),
the comparisons are carried out according to [comparison rules](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenlogexp_rules.htm).
The following code snippet shows a selection of possible expressions and operands of such expressions using a big `IF` statement. Certainly, such a huge statement is far from ideal. Here, the intention is to just cover many syntax options in one go for demonstration purposes. For more information on built-in functions, you can refer to the [Misc Built-In Functions](/24_Misc_Builtin_Functions.md) cheat sheet.

- `params`: Parameter list or table
- Incorrectly provided function module names or parameters are not checked until runtime
- Unlike method calls, you cannot specify inline declarations as actual parameters.
- Regarding dynamic function module calls: Static and dynamic function module calls are syntactically identical. In a static call, the function module is specified as a character literal or a constant, with parameters passed statically. Conversely, in a dynamic call, the function module's name is specified in a variable, with parameters passed dynamically. For dynamic calls, you can utilize the `CL_ABAP_DYN_PRG` as shown in the [Misc ABAP Classes cheat sheet](22_Misc_ABAP_Classes.md).

- When a function module call is made, the system field `sy-subrc` is set to 0. If a non-class-based exception is raised and a value is assigned to handle it, this value updates `sy-subrc`.
Example function module calls with parameter passing and exception handling:
