Convert operand to stack variable

 Action    name: OpStackVariable
This command converts immediate operand(s) type of the current instruction to an offset to stack variables, i.e. a local variable or function argument in the stack.

You need to define stack variables before using this command.

If the current operand is based on the value of the stack pointer ([ESP+xxx]) and the SP value is traced incorrectly, then you need to correct SP value using change stack pointer command.

If a range is selected using the anchor, IDA will perform 'en masse' conversion. It will convert immediate operands of all instructions in the selected range to stack variables. However, IDA will ask you first the lower and upper limits of immediate operand value. If the operand value is >= lower limit and <= upper limit then the operand will be converted to stack variable, otherwise it will be left unmodified.

When you use this command, IDA deletes the manually entered operand.

If the cursor is on the first operand (the cursor is before ',') then the first operand will be affected; otherwise all other operands will be affected.
