The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:

3E <int32>	ble target	Branch to the target instruction at the specified offset if the first value is less than or equal to the second value.

The stack transitional behavior, in sequential order, is:

[The 'ordered' type of list has not been implemented in the ECMA stylesheet.]

The ble instruction transfers control to the specified target instruction if value1 is less than or equal to value2. The effect is identical to performing a cgt instruction (cgt.un for floats) followed by a brfalse branch to the specific target instruction. The target instruction is represented as a 4-byte signed offset from the beginning of the instruction following the current instruction.

If the target instruction has one or more prefix codes, control can only be transferred to the first of these prefixes. Control transfers into and out of try, catch, filter, and finally blocks cannot be performed by this instruction.

The following ILGenerator.Emit(OpCode) method overload can use the ble opcode:
