Variable, Token, Function Question

[ccstone]

Hey Alex,

Take a look at this:

TIP: Understanding KM Variables, Tokens, & Functions

Keep in mind that when you place the cursor into an input field, you will see a visual cue in the upper right corner of the field:

C == Calculation
T == Text
V == Variable

Calculation Fields can take Functions and bare variable names

Text Fields can take Text-Tokens and variables in the format:
⠀⠀⠀%Variable%YourVariableName%

Variable Fields should be self-explanatory.

@aeg

Variables in the format of: %Variable%Var10% vs ==%Var10%== vs Var10

Never use the highlighted format for a variable. KM allows it, but you won't be able to tell by looking what's a text-token and what's a variable.

Always use the %Variable%Var10% format, except in calculation fields and variable fields.

@aeg

%Token%LongDate%

There is no such format for tokens.

@aeg

vs ==LongDate==

That's meaningless. It is only valid within the context of a text-token.

@aeg

WINDOWCOUNT() vs %WINDOWCOUNT()%

Functions are NEVER tokenized.

See these menu items:

See the Insert by Name submenus for each.

@aeg

… am I correct with the "the only way to use a function in an action is..." part?

Nyet.

You can use functions in text fields IF you use the calculate text-token:

%Calculate%WINDOWCOUNT()%

@aeg

SET VARIABLE Coords to CALCULATION WINDOW()

There is no such function as WINDOW().

Try:

WINDOW(left) or WINDOW(2,left) or WINDOW(2,right)

@aeg

Of course I can figure this out by trial and error but that takes time every time and I can't remember which one worked the next time I need to use it.

Take notes. Make yourself a cheatsheet.
