STI (Set-Increment) is one of the opcodes in the DCPU-16 specification. It represents copying a value into a register or a memory location, then incrementing the I and J registers.

[edit] Usage
STI loc, val
STI sets loc to the value val, and increments I and J by 1.
It is common as the final instruction in a loop before jumping back to the beginning of the loop.
[edit] Signing dependence
All of STI's functions are sign-agnostic, working correctly on both signed and unsigned values.
[edit] EX register usage
STI does not read or write to the EX register.
[edit] Processing
In binary machine code, this Basic opcode's five-bit representation is: 0b1 1110 (0x1e)
The instruction takes two cycles to execute, plus any additional cycles necessary to evaluate the arguments.
