PUT Location, { WORD } Value { , { WORD } Value... }
Function
Write one or more values to the Scratch Pad RAM (SPRAM), starting at
Location.
• Location is a variable/constant/expression (0 – 62 for BS2e and
BS2sx, and 0 – 126 for BS2p, BS2pe, and BS2px) that specifies the
SPRAM location to write to.
• Value is a variable/constant/expression (0 – 255, or 0 – 65535 if
using the optional WORD modifier) to store in the SPRAM.
Quick Facts

NOTE: When the WORD modifier
is used, the low byte of the value
is written to Location, the high
byte to Location + 1.

Syntax Options
Multiple sequential variables may be written to the Scratch Pad RAM.
The optional WORD modifier may be specified to store 16-bit values.
Explanation
The PUT command writes value into the specified Scratch Pad RAM
(SPRAM) location. All values in the general-purpose locations can be
written to from within any of the 8 program slots.
SPRAM 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 write the value 100 to
location 25, read it back out with GET, and display it:
U
