command call mnemonic operand

Calls the given operand (address or function), jumps to the given operand then returns.

Note: A RET must be hit for a CALL to work properly, best to use JMPs if unsure.

Command Parameters

Parameter Description
mnemonic OPTIONAL The preferred size of the assembled address
operand The address or symbol to call


Examples

call +1A   // Call from end of command to +1A (hex).
call 00123ABC   // Call the address.
call 0000123456ABCDEF   // Call the address.
call eax   // Call the value of eax.
call rax   // Call the value of rax.
call someSymbol   // Call the user defined symbol.
call someLabel   // Call the label.
call short someLabel   // Call the label with short byte code.
call long someLabel   // Call the label with full address.
call @b   // Call back the closest anonymous label (@@:).
call @f   // Call forward the closest anonymous label (@@:).
