isNumber
|
Purpose
|
Tests a value to see if it is a valid number.
|
|
Syntax
|
isNumber storageVar {value}
storageVar: A variable to hold the result of the test.
{value}: The value to be tested.
|
|
Notes
|
"storageVar" will be set to TRUE (1) if "value" is a number, otherwise it will be set to FALSE (0).
It is often good practice to test values entered by the user if you expect them to be numeric.

Example
|
:PlanetsPerSector
getInput $value "Enter number of planets per sector"
isNumber $test $value
if ($test = 0)
echo ANSI_15 "**Value must be a number*"
goto :PlanetsPerSector
end
setVar $build_planetsPerSector $value
saveVar $build_planetsPerSector
