The LET command is used to assign value to a specific
variable. The expression is evaluated and assigned to each variable
in the variable list.
Format
LET <variable> [,<variable>]* = <expression>
The
variable types must match the expression type or an error message
will be displayed.
Error: Poorly formed expression.
When
a value is assigned to a string variable with a sub-string qualifier,
it replaces the value of the sub-string qualifier. The length of
the value of the string variable may change as a result of this
replacement.
Parameters
N/A
Example
This is an example of how to use the
LET
command:
10 LET A$= "1234"
15 LET A$(2:3)= "55" ! A$ NOW = 1554
20 LET A$(2:3)= "" ! A$ NOW = 14
10 LET A$= "1234"
15 LET A$(2:3)= A$(1:2) ! A$ NOW = 1124
10 LET A$= "1234"
15 LET A$(2:1)= "5" ! A$ NOW = 15234
Comments
This can be an interactive command that takes effect as soon
as it is received by the printer, or a program command that is preceded
by a line number.
