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
<source lang="basic">
10 LET A£ = "FOO"
20 PRINT A£[2,3]
</source>
would print <code>OO</code>
This syntax was also supported on the left-hand side of an assignment, so
<source lang="basic">
10 LET A£ = "FOO"
20 LET A£[2,2] = "BAR"
30 PRINT A£
</source>
would print <code>FBARO</code>

10 DIM A(3,3)
20 MAT READ A

90 MAT D=INV(C)
100 MAT PRINT D,
