[3] Variables with “*” (asterisk) (indirect specification)
An “*” (asterisk) is used to specify a variable.
In the following example, the content of variable box 1 will be put in variable box 2. If variable box
1 contains “1234,” then “1234” will be put in variable box 2.
Command Operand 1 Operand 2
LET 1 1234
Command Operand 1 Operand 2
LET 2 *1
The above use of variables is called “indirect specification.”
An “*” is also used when indirectly specifying a symbol variable (refer to 1-8, “Symbols”).
Command Operand 1 Operand 2
LET ABC 1 Put 1 in variable ABC.
LET BCD 2 Put 2 in variable BCD.
