Limitations S and S+1 must be within the same data area. R and R+1 must be within the
same data area. S and S+1 must be BCD and must be between 0 and
35,999,999 seconds.
Description HMS(66) is used to convert time notation in seconds to an equivalent in hours/
minutes/seconds.
The number of seconds designated in S and S+1 is converted to hours/minutes/
seconds and placed in R and R+1.
For the results, the seconds is placed in bits 00 through 07 and the minutes is
placed in bits 08 through 15 of R. The hours is placed in R+1. The maximum will
be 9,999 hours, 59 minutes, and 59 seconds.
Flags ER: S and S+1 or R and R+1 are not in the same data area.
S and/or S+1 do not contain BCD or exceed 36,000,000 seconds.
Indirectly addressed DM word is non-existent. (Content of DM word is
not BCD, or the DM area boundary has been exceeded.)
EQ: Turns ON when the result is zero.
Example When 00000 is OFF (i.e., when the execution condition is ON), the following
instruction would convert the seconds given in HR 12 and HR 13 to hours, min-
utes, and seconds and store the results in DM 0100 and DM 0101 as shown.
