Ignoring Spaces - IGNORESPACES

 

By default, spaces are seen as regular characters and are included in variable assignments.  E.g. The following line..
 
 Let>a = 5
 
 .. would create a variable called "a " with the value " 5".
 
 Normally, therefore, you should use:
 
 Let>a=5
  
 But experienced programmers are used to the language ignoring spaces.  This can be achieved by setting IGNORESPACES to 1:
 
 Let>IGNORESPACES=1
Let>a = 5
  
 This would set variable "a" to the value 5.
 
 If spaces are ignored then strings that need preceding spaces will need to be delimited.  To do this use {"string"}
 
 Try stepping through the example below with the Debugger and Watch List open.  

 

Example
  
 Let>VAREXPLICIT=1
 Let>IGNORESPACES=1
  
 Let>a = 5
 Let>b = 22
  
 Input>c, Enter a number:, 0
 If> %c% > 0
  Let> d = {%a% + %b% * %c%}
 Else
  Let> d = {%a% * %b%}
 Endif
 MessageModal> Answer: %d%
  
 //With IGNORESPACES=1 do the following if you want leading/trailing spaces in a string
 Let>string_with_spaces = {"  I want preceding spaces  "}
 MessageModal> %string_with_spaces%
  
 //Or just switch IGNORESPACES off and on
 Let>IGNORESPACES=0
 MessageModal>  Need these leading spaces
 Let>IGNORESPACES=1
  
 //Inline Expressions:
 MessageModal>{"  I want preceding spaces"}
  
 //Sum:
 MessageModal>{5 + 4}
  
 //Embed a complex expression within the string as you would a variable:
 MessageModal>W Pos: %{Pos("W","Hello World")}%
