Hello everyone,
how can I send output to the screen from a running script or tcl, in such a way that if a loop is executing I will see the rolling counter on my screen as the records are processed in the loop. I do not want the screen to scroll, though. In other words can a var's value be painted... (2 Replies)

Hi!
Can anyone explain this? The counter CDR_count should go on forever, but it suddenly resets at every step of the FOR loop (I know this because $_file has exactly 378 records). However, the counter reset is OUTSIDE the FOR loop. What's going on??

so, the above counter doesn't work, already tried both -lt & -gt, and changed || to &&

Description
The and functions return trigonometric functions of radian arguments x for double data types.
The and functions return trigonometric functions for float data types.
The and functions return the arc sine in the range -pi/2 to pi/2 for double and float data types, respectively.
The and functions return the arc cosine in the range 0 to pi for double and float data types, respectively.
The and functions return the arc tangent in the range -pi/2 to pi/2 for double and float data types, respectively.
The and functions return the arc tangent of y/x in the range -pi to using the signs of both arguments to determine the quadrant of the
return value for double and float data types, respectively.
Error (due to roundoff)
When P stands for the number stored in the computer in place of pi = 3.14159 26535 89793 23846 26433 ... . and "trig" stands for one of
"sin", "cos" or "tan", then the expression "trig(x)" in a program actually produces an approximation to trig(x*pi/P), and "atrig(x)"
approximates (P/pi)*atrig(x). The approximations are close.
P differs from pi by a fraction of an ulp; the difference is apparent only if the argument x is huge, and even then the difference is
likely to be swamped by the uncertainty in x. Every trigonometric identity that does not involve pi explicitly is satisfied equally well
regardless of whether P = pi. For example, sin(x)**2+cos(x)**2 = 1 and sin(2x) = 2sin(x)cos(x) to within a few ulps regardless of how big
x is. Therefore, the difference between P and pi is unlikely to effect scientific and engineering computations.
Return Values
All the double functions return NaN if NaN is passed in.
If |x| > 1 then (x) and (x) will return the default quiet NaN.
The function defines (0,0) = NaN.
