Add bending line (main definition of the bending line)
C call:
C CALL PVB440 (IN,RW,RH,RL,IT,ICL,ICT,R1,R2,R3,I1,I2,I3,BT,IRET)
C
C The following variables must be defined beforehand:
C
C IN : Bend number (1,2,3,...)
C RW : Bend angle (+90.0,-90.0,...)
C RH : Text height for bend angle (0=auto)
C RL : Shifting the text (0=central)
C IT : Text type for the output
C Negative = in the line, Positive = beside the line
C 100 = Bend number
C 10 = Bend angle
C 1 = Bend text
C 110 = only bend number + angle
C ICL : Colour for bend line (0=auto)
C ICT : Colour for text (0=auto)
C R1-R3 : Addition real (currently not used)
C I1-I3 : Addition integer
C BT : Bend text
C IRET : is not evaluated, but must be specified
