CIGAL Reference Manual, Chapter 6 (RealTime): r_iflt
r_iflt -- Test whether 1 short integer is less than another
usage: r_iflt opflg eflag ltime Value Value2
R_IFLT is a REALTIME operator. It must be part of an R_IFLT/R_ENDIF or R_IFLT/R_ELSE/R_ENDIF block specification. The operation compares integer VALUE1 to integer VALUE2. If VALUE1 is less than VALUE2 the program will execute the operations appearing between this operation and the corresponding R_ELSE or R_ENDIF line, whichever comes first. If the AND result is zero, control will immediately jump to the corresponding R_ELSE or R_ENDIF line, whichever comes first.
