612 Appendix A: System Routines - Graphing StepCk Declaration: void StepCk (BCD16 * indep) Category: Graphing Description: Verifies that the input min, max, and step values in the array pointed to by indep are valid values for the independent variable in parametric mode (tmin, tmax, and tstep) or polar mode (θmin, θmax, and θstep). The function will return to the calling routine if the values are valid, otherwise an error is thrown. Inputs: indep - Pointer to an array of BCD16 floating-point values where indep[0] = min, indep[1] = max, and indep[2] = step. Outputs: None Assumptions: None Side Effects: An error is thrown if the input values are not valid for the independent variable in parametric mode or polar mode, such as the step value being negative when it should have been positive for the given min and max. Availability: All versions of the TI-89 / TI-92 Plus. TI-89 / TI-92 Plus Differences: None See Also: CkValidDelta Example: if( gr_active->graph_mode == GR_PAR ) /* parametric mode - make sure viewing window variables tmin,tmax,tstep OK */ StepCk(&((gr_active->rngp)[GR_TMIN])); TI-89 / TI-92 Plus Developer Guide Not for Distribution Beta Version January 26, 2001
