CLOG
computation
CLOG.SUM(001.002.003)
Determines the sum of [001], [002], and [003].
CLOG.MAX(001.002.003)
Determines the maximum value among [001], [002], and [003].
CLOG.MIN(001.002.003)
Determines the minimum value among [001], [002], and [003].
CLOG.AVE(001.002.003)
Determines the average value of [001], [002], and [003].
CLOG.P-P(001.002.003)
Determines the difference between the maximum value and
the minimum values among [001], [002], and [003].
Special
computation:
PRE(001) Determines the previous value of [001].
101=HOLD(001.GT.K01):TLOG.SUM(001)
Under normal conditions, TLOG.SUM(001) is carried out to
derive the computed value. When [001] exceeds K01, the
previous computed value is held.
K01
Explanation
HOLD(a):b
When a is zero, b is carried out to derive the computed value.
Otherwise, the previous computed value is held.
RESET(101.GT.K01):TLOG.SUM(001)
Under normal conditions, TLOG.SUM(001) is carried out to
derive the computed value. When [101] exceeds K01, the
previous computed value is reset, and TLOG.SUM(001) is
carried out.
K01
Reset
Explanation
RESET(a):b
When a is zero, b is carried out to derive the computed value.
Otherwise, the previous computed value is reset, and b is
carried out to derive the computed value.
CARRY(K01):TLOG.SUM(001)
Under normal conditions, TLOG.SUM(001) is carried out
to derive the computed value. When the computed value is
greater than or equal to K01, the computed result is the excess
(computed value – K01).
K01
Explanation
CARRY(a):b
Only TLOG.SUM can be specified for b. If the computed value
X of b is less than a, the computed result is X. If X is greater
than or equal to a, the computed result is the excess (X – a).
Conditional
equation
[001.GT.K01?001:001+002]
When [001] is greater than K01, the computed value is set to
the value of [001].[001]Otherwise, the computed value is set to
the value of [001] + [002].
Explanation
[a?b:c]
If the computed result of a is nonzero, b is carried out.
Otherwise, c is carried out.
