Let's try to pin that down. Dieter already gave a hint: the accuracy in register E and the display precision should match.
But since the program I uses program C I first want to know if you get the same result for this example:

XEQ T ENTER
K?
7
R/S

XEQ C ENTER
X?
1.5
R/S
0.911351

This is just to make sure that program C works fine.

If that's okay please make sure to set FIX 3 and E = 1E-3 before running the next example.

XEQ I ENTER
X?
0.99
R/S
2.997

It should flicker about four times INTEGRATING and then display the result.

If the integration doesn't stop then please add an R/S command between lines I007 and I008 and report both the value displayed and the contents of register X (use VIEW X). Just use R/S to run the next round of the loop for a couple of times.

Hopefully this helps to find the problem.

Cheers
Thomas

PS: Thanks for posting the HP-67 programs. It's always interesting to learn something new. For instance I didn't know about the formula used to calculate the CDF of the Student's t-distribution. But then I must admit that I'm not familiar with statistics. Still I'm curious how they came up with that formula.
