Especially in complex cases, comments in algorithms can be very helpful.
As of V12 SP2, these can be added in PARTdesigner in the Variable Manager, both in the Formula [Equation] dialog area and in the Characteristic Algorithm [Attribute algorithm] dialog box.
Comments start with character # and do end by the end of line
Comments starting behind an expression (e.g. ELSE) get automatically moved into the line before.
Comments are not allowed to contain an uneven amount of ' (quotes)
Comments can be added both in the Formula [Equation] dialog area and in the Characteristic algorithm [Attribute algorithm] dialog box.
