Dislin Manual Question

[maxg...@gmail.com]

Dear Helmut

In the current dislin manual I read

The call is:
CALL SURFCP (ZFUN, IXDIM, TMIN, TMAX, TSTEP, UMIN, UMAX, USTEP)
level 3
or:
void surfcp ((float) (*zfun()), float tmin, float tmax, float tstep, float umin, float umax, float );

ZFUN
is the name of a FUNCTION subroutine with the formal parameters X, Y and IOPT. If IOPT = 1, ZFUN should return the X-coordinate of the parametric function, if IOPT = 2, ZFUN should return the Y-coordinate and if IOPT = 3, ZFUN should return the Z-coordinate.
TMIN, TMAX, TSTEP
define the range and step size of the first parameter.

I think the right statement should be:

...is the name of a FUNCTION subroutine with the formal parameters T, U and IOPT.....

or

double (*zfun)(double t,double u,int32_t iopt)

Am I right? Am I wrong?

regards

Max

Dear Max,

you are right. Thank you for the hint, I will correct it with the next upgrade.

With best regards,
