Editing ASIC programming language (section)

=== Control Structures ===
A boolean condition may be only a comparison of numbers or strings, but not a comparison of combined expressions. A literal cannot be the left operand of comparison (e.g. can be <code>X = 2</code>, not <code>2 = X</code>).

==== Decisions ====
After <code>THEN</code>, there may be a sequence of statements delimited by <code>ELSE</code> or <code>ENDIF</code>. An example:
<syntaxhighlight lang="basic">
IF X < 0 THEN
  PRINT "Negative"
ELSE
  PRINT "Non-negative"
ENDIF
</syntaxhighlight>
Contrary to other BASICs, statements cannot be put between <code>THEN</code> and the end of the line.

An if-statement can realize the conditional jump. In this case, after <code>THEN</code> there may be a label.

==== Looping ====
In <code>FOR</code>, after <code>TO</code> there may be only a number - literal or variable - but not a combined expression. The <code>STEP</code> clause does not exist in ASIC.

==== Branching ====
In a <code>GOTO</code> statement, the label must be followed by a colon.

==== Subroutines ====
In a <code>GOSUB</code> statement, the label must be followed by a colon.
