Free42 Programming Question (HP42S)

[Thomas Okken]

You can use XEQ "ATOX" to access the ATOX function. When you enter XEQ "name", the calculator will first search for a LBL "name", and if it doesn't find one, it will then look for "name" in the catalog of built-in functions (CATALOG->FCN). If you do this in PRGM mode, it will store ATOX in the program, not XEQ "ATOX".

You can also access all built-in functions by executing them from CATALOG->FCN, but you probably won't usually want to do that, since that menu has 42 rows, so finding functions that aren't close to the ends of the list is a bit cumbersome.
