LET
Statement/Command
LET is used to assign a value to a variable. In this version of BASIC, LET cannot be omitted in an assignment statement.
How to use LET
LET normally forms a statement in a program but may be used as a direct command. It is followed by a numeric or string variable, an equals sign, and then a value. The value may be numeric or string, depending on the variable preceding LET, for example
60 LET x=x+1
80 LET a$="Correct"
The value is then assigned to the variable.
Note that simple variables are undefined until assigned values by LET, READ or INPUT. Array variables however are initialised to 0 or a null string ("") by DIM.
Format
- LET num-var = num-expr
- LET string-var = num-expr
