Line 124:

Support for strings was more limited, with only one function, <code>LEN</code>, which returned the length of the string parameter. Sub-strings were supported with square brackets, so <code>A£[2,3]</code> referred to the sub-string of the string <code>A£</code> from the 2nd character to the 3rd character inclusive, so

<syntaxhighlight lang="basic">

10 LET A£ = "FOO"

20 PRINT A£[2,3]

</syntaxhighlight>

would print <code>OO</code>

Line 131:

This syntax was also supported on the left-hand side of an assignment, so

<syntaxhighlight lang="basic">

10 LET A£ = "FOO"

20 LET A£[2,2] = "BAR"

30 PRINT A£

</syntaxhighlight>

would print <code>FBARO</code>
