class	ArrayProcess	Applies all sub-actors to each of the array elements.
class	Block	Blocks the propagation of tokens if the condition evaluates to 'true', therefore acts like the 'continue' control statement. In case of integer or double tokens that arrive at the input, these can be accessed in the expression via 'X'. The following grammar is used for evaluating the boolean expressions (depends on the selected condition): expr_list ::= '=' expr_list expr_part | expr_part ; expr_part ::= expr ; expr ::= ( expr ) # data types | number | string | boolean | date # constants | true | false | pi | e | now() | today() # negating numeric value | -expr # comparisons | expr < expr | expr <= expr | expr > expr | expr >= expr | expr = expr | expr != expr (or: expr <> expr) # boolean operations | ! expr (or: not expr) | expr & expr (or: expr and expr) | expr | expr (or: expr or expr) | if[else] ( expr , expr (if true) , expr (if false) ) | ifmissing ( variable , expr (default value if variable is missing) ) # arithmetics | expr + expr | expr - expr | expr * expr | expr / expr | expr ^ expr (power of) | expr % expr (modulo) ; # numeric functions | abs ( expr ) | sqrt ( expr ) | log ( expr ) | exp ( expr ) | sin ( expr ) | cos ( expr ) | tan ( expr ) | rint ( expr ) | floor ( expr ) | pow[er] ( expr , expr ) | ceil ( expr ) | year ( expr ) | month ( expr ) | day ( expr ) | hour ( expr ) | minute ( expr ) | second ( expr ) | weekday ( expr ) | weeknum ( expr ) # string functions | substr ( expr , start [, end] ) | left ( expr , len ) | mid ( expr , start , len ) | right ( expr , len ) | rept ( expr , count ) | concatenate ( expr1 , expr2 [, expr3-5] ) | lower[case] ( expr ) | upper[case] ( expr ) | trim ( expr ) | matches ( expr , regexp ) | trim ( expr ) | len[gth] ( str ) | find ( search , expr [, pos] ) | replace ( str , pos , len , newstr ) | substitute ( str , find , replace [, occurrences] ) ; Notes: - Variables are either all upper case letters (e.g., "ABC") or any character apart from "]" enclosed by "[" and "]" (e.g., "[Hello World]"). - 'start' and 'end' for function 'substr' are indices that start at 1. - Index 'end' for function 'substr' is excluded (like Java's 'String.substring(int,int)' method) - Line comments start with '#' - Semi-colons (';') or commas (',') can be used as separator in the formulas, e.g., 'pow(2,2)' is equivalent to 'pow(2;2)' - dates have to be of format 'yyyy-MM-dd' or 'yyyy-MM-dd HH:mm:ss' - times have to be of format 'HH:mm:ss' or 'yyyy-MM-dd HH:mm:ss' - the characters in square brackets in function names are optional: e.g.
