Moeller GmbH, IM-S Schutzvermerk nach DIN 34 beachten Variable names must not contain national symbols (ä, ü, ö), blanks or hyphens ! Variable names must not begin with a number ! Variable names and file (program) names MUST differ ! Keywords must not be used as variable names ! Sample: A variable named LT (e.g. for the function lamp test) will lead to an error message because LT is the reserved keyword for a comparator ! (LT=Less Than) Stör-M1:BOOL Stoer_M1:BOOL 1_Start:BOOL Start_1:BOOL Pump:BOOL Pump1:BOOL Pump.POE LT:BOOL L_Test:BOOL Hints for the use of identifiers

Moeller GmbH, IM-S Schutzvermerk nach DIN 34 beachten Chose your variable name in a way that they are self-explanatory. Use a capital letter as the first letter and use small letter for the rest. Separate variable names consisting of several word by underscores between the words and start each word with a capital letter. When working with brackets please use indentions for each level. e.g. use one TAB for each new bracket level. Always put jump labels in a separate line and highlight them by e.g. framing them with comments All below mentioned hints serve the purpose of making your programs easy to read and give them a well-defined structure: Hints for the creation of programs
