==== 7.5.63 istore ====

Store int into local variable 

Format 

istore 

index 

Forms 

istore = 42 (0x2a) 

Stack 

..., value.word1, value.word2 -> ... 

Description 

The index is an unsigned byte. Both index and index + 1 must be a valid index into the local variables of the current frame ([[3.5_Frames| Section 3.5, Frames]]). The value on top of the operand stack must be of type int. It is popped from the operand stack, and the local variables at index and index + 1 are set to value. 

Notes 

If a virtual machine does not support the int data type, the istore instruction will not be available.
