Usually, Size Error means you're trying to access a numbered register that doesn'texist, i.e. the SIZE setting (in the MODES menu) is set too low. By default, thesetting is SIZE 0025, which means you have registers numbered from 00 through 24.
When even RCL 00 returns Size Error, however, that usually means that the REGSmatrix was inadvertently deleted. This also causes all statistical functions tofail, since they all use numbered registers to access the summation data.
To fix this, and restore REGS to its default size, say SIZE 0025: Shift+/−▼Σ+0025.
How do I assign SST↓ (Step Into) to the CUSTOM menu?
SST↓, also known as Step Into, introduced in Free42 2.1, is not a new function;rather, it is a new spelling of the existing SST function. Since functions arelisted in the FCN catalog by their primary spelling only, this leads to the questionof how to assign SST↓ to the CUSTOM menu, with the arrow.The answer is to spell it out using the ALPHA menu: Shift1ENTERLN1/xLN1/xLN√x▼1/x√xENTERΣ+
(Replace Σ+ with whichever key in the CUSTOM menu you want to assign SST↓ to.)

Why is nothing showing up in the Print-Out?
Like the HP-42S, Free42 is in Printer Off mode by default. To enable printing,use the PRON function in the PRINT menu: Shift−▲Σ+.
