LET |
Assign Value to Variable |
[LET] var[$]=expression,[var[$]=expression,...]
|
var |
Numeric or string variable to be set to the value of the expression. |
|
expression |
Numeric or string expression whose value will be assigned to the variable. |
Use the LET directive to set a variable to the value of an expression. If the variable is numeric, use a numeric expression. If it is a string variable, use a string expression. You can use substrings with string variables. (Specify the starting position and optional length.)
The word L E T is optional in Command mode. PxPlus assumes use of the LET directive when it encounters a directive starting with a variable. You can include multiple LET directives in one statement by using comma delimiters. In this case, if you use the word L E T, it only occurs once before the first assignment.
You can initialize, copy or manipulate a complete array by specifying {ALL} following the variable name. {ALL} can be used on both sides of an equation.
0080 let A$="THIS IS AN EXAMPLE"
0100 A$(1,4)="WHAT",A$(19)="!",Z$=""
0110 A$(5,4)=Z$
If Z$ is more than 4 characters, A$(5,4) is set as the first 4 characters of Z$. If Z$ is less than 4 characters, the A$(5,4) value is Z$ plus space padding up to a length of 4 characters:
->run
->?A$
WHAT AN EXAMPLE!
Z4=A+4.5,Z5=Z4*.85
let D$=day,T=tim*3600
dim A[30]; let A{all}=A{all}*4
