2.8.2 String Functions (StringFunctionCall)

scopy( StringExpression , IntExpression₁ , IntExpression₂ )

returns a substring of StringExpression starting at the position given by IntExpression₁. (Note that we find the first character in a string at position 0.)
IntExpression₂ 0 represents the length of the substring. Make sure that it is still completely part of the string; more precise,

IntExpression₁ + IntExpression₂ len(StringExpression)

must be satisfied.

Example 21:

scopy("state 13",6,2)      13
scopy("1234567890",3,1)     4

itos( IntExpression )

converts IntExpression into a string constant. Leading zeros in IntExpression are not allowed.

Example 22:

itos(-10203) "-10203"

Suppose that str is a string variable with contents "3 happy corners of a triangle".

itos(stoi(str)-1) + " corners?!" "2 corners?!"
