Function
Read value from Scratch Pad RAM Location and store in Variable.
• Location is a variable/constant/expression (0 – 63 for Bs2e and BS2sx
and 0 – 127 for BS2p) that specifies the Scratch Pad RAM location to
read from.
• Variable is a variable (usually a byte) to store the value into.

Explanation
The GET command reads a byte-sized value from the specified Scratch
Pad RAM location and stores it into Variable. All values in all locations can
be retrieved from within any of the 8 program slots.
Scratch Pad RAM is useful for passing data to programs in other program
slots and for additional workspace. It is different than regular RAM in
that symbol names cannot be assigned directly to locations and each
location is always configured as a byte only. The following code will read
the value at location 25, store it in a variable called Temp and display it:
Temp VAR
GET 25, Temp
DEBUG DEC Temp
Scratch Pad RAM locations 0 though 62 are available for general use. The
highest location (63 for BS2e and BS2sx and 127 for the BS2p) is a special,
read-only, location that always contains the number of the currently
running program slot. On the BS2p, the upper nibble of location 127 also
