SHORT :
The SHORT operator denoted to the assembler that only one byte is needed to code the displacement for a jump (for example displacement is within -128 to +127 bytes from the address of the byte next to the jump opcode). This process of specifying the jump address saves the memory. Or else, the assembler may reserve two bytes for the displacement. The sentence structure of the statement is as given below.
JMP SHORT LABEL
TYPE :
The TYPE operator directs the assembler to decide the data type of the mention label and replaces the 'TYPE label' by the decided data type. For the particular word type variable, the data type is 2, for double word type, it is four, and for byte type, it is one. Imagine, the STRING is a word array. The instruction TYPE STRING, MOV AX, moves the value 0002H in AX.
GLOBAL :
The, variables, labels, constants or procedures declared GLOBAL can be used by other modules of the program. Once a variable is declared GLOBAL, it may be used by any module in the program. The following statement declares the process ROUTINE as a global label.
