HP 35S Error Handling

[JeremyBeck]

Thanks for the reply Dieter. I did try as you suggested and allocated the first 100 registers by storing 0 in an (i) of 100. this stopped the error when recalling (i)50 for example. a zero is returned instead of INVALID(I). I will just have to keep track of what I am entering so as to get the correct results.

One other question I had is that I am working on several programs (one of which is a program to store a point with coordinates in storage registers 1 through 100 as a vector in the format of [northing, easting, elevation]). the program works as intended but I would like to share my programs for other users who might find them helpful. Would this forum be the place for that?
