In ugBASIC (like CBM BASIC) you do not need to isolate keywords from each other or from other identifiers with any separator, like spaces.

Identifiers

Identifiers are used to give a name to labels, variables, constants, procedures and functions. You may choose any name for identifier. Anyway, you have to follow some rules:

Statements

Statements and commands can be separated using the colon symbol (:) character, and can end with LF or CR+LF characters. The separator is not required if there's only one statement in one line, as the following example:

 WHILE NOT finished : PRINT "continue" : WEND
 WHILE NOT finished
    PRINT "continue"
 WEND

Comments

If you begin a line with single quote (') character, or put it after colon symbol, it will be considered a comment until the end of the line. The same for the REM command, that is used to begin a comment.

 ' comment
 REM comment
 line = 1 :' comment
 line = 1 :REM comment

Whitespace

Whitespace (e.g. spaces and tabs) are ignored, since they are not needed. You are encouraged to use them if you need to make make the program more readable, or to remove it if you need to join competitions where number of lines is an important factor.
