Whitespace Variable Display Problem

[Willaim Mitchell]

// Pointer Location and Pixel Color when CTRL-P is typed
GETCURSORPOS> X,Y
GETPixelCOLOR>X,Y,Color
MessageModal>X,%X%,Y,%Y%, Color,%Color%


If a leading blank is present when X is defined, a message will show the variable name (X) where the value should be.
Message Display after CTRL-P = X,%X%,Y,581, Color,14265756

Getting rid of the blank following "GETCURSORPOS>" fixes this problem however the value of X is correct and usable in expressions even when the display problem is present.

Macro Scheduler recognizes spaces as "real" characters. They can not be used as delimiters, or space to make easier reading.
Let> x is not the same as Let>x.

This is true, anywhere on the line, escpecilly common error around equal signs.
Let>a = 15 is not the same as Let>a=15, and Let>a= 15 is also different.

Initially you may find this a problem, but will soon come to value the benefits of the literal variables.

You should also look into the use of IGNORESPACES. This setting will allow you to use spaces in some instances with no change in the value.

This is right out of the help file

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.

Thanks for the IGNORESPACES suggestion. I will begin using it.

There still seems to be a problem with consistency because
GETCURSORPOS> X,Y
GETPixelCOLOR> X,Y,Color
MessageModal> X,% X%,Y,%Y%,Color,%Color%

has the same display error as when I tried to display %X%...that is the message shows the variable name instead of the value even if I use " X" everywhere.

In a message, unless a variable is the ONLY item in the message, the variable must be surrounded by percents.

Try:
MessageModal> %X%,% X%,%Y%,% Y%,Color,%Color%

You have a space here: % X%. The line should be:

MessageModal> X,%X%,Y,%Y%,Color,%Color%

i.e. to use variables within strings they must have % symbols around them, with no spaces between the % symbols and the variable name.
