is there a substitute key on the 15c for x>0 which was on the 11c.

Look at the back panel for details of the TEST instruction. - Pauli

I had a program with this line init on my 11c so i need the corresponding keyin so that the program will work on my 15c.

I tried using g test 1 (x>0) but the program still does not work.

Jim, I'd suggest you show a listing of your program here and tell us what "does not work". Else try single-stepping through your program and check the values on the stack. AFAIK calculators aren't mean, so the problem sits in front of them usually ;)

Jim,
The 15c has additional tests compared to the 11c. Unlike the 11c however, only two of the tests are directly labeled and keyed. The other ten are called using sequence g TEST n.
11C has 8 tests, all in the 10th column of keys:
For the 15c, look on the back of the calculator and you will see a table thus: ERROR TEST MATRIX So to get "X > 0" you key in g TEST n which is g followed by the minus key, followed by the number 1. I hope that helps, Bill

Hi Jim,

Jim -- g TEST 1 on the HP-15C indeed provides the "x > 0 ?" conditional test listed directly on the HP-11C. The four conditional tests of equality and inequality on the HP-15C utilize both parts of a complex number, so they might act unexpectedly in complex mode (g SF 8). However, "x > 0?" is not one of those tests. If difficulties persist, I'd echo Walter's suggestions for you to post the troublesome code and be more specific about "does not work". -- KS
