Known Limitations
The following three cases describe limitations where the HP 15c may not
work as expected.
G V With Negative Number
The HP 15c supports indirect branching, by storing either a label index (as
a positive number) or a line number (as a negative number) in R
I
, and then
calling t V. However, when instead branching to a subroutine with
G V, only a label index (a positive number) is supported. Using a
negative number (for a line number) will result in unexpected behavior.
Conditional as Last Line in Program
When the last line of a program is a conditional test that could skip the
next line (either an explicit conditional, such as ~, or an implicit
conditional, such as the “User” l A with a matrix as described on
page 176), unexpected behavior will result. To avoid this, put a n as
the last line in the program after the conditional statement.
” and Stack Lift
Normally, after digit entry termination, ” enables stack lift, as
described in Appendix B. However, if the value in the X-register is 0, stack
lift will not be enabled.
