Optional separator used for readability in If blocks.
If expression [Then]
Statements...
Endif
If expression [Then] Statements...
The keyword Then allows separation of expression and statement(s); however, its only function is to aid readability according to programmer preference and it can be safely left out.
' Simple variable check: If a = 1 Then Print "a equals one" Endif' Single-line example, using Then: If a = 1 Then Print "a equals one"' The 'Then' separator is optional: If a = 1 Print "a equals one"
