insert(str1, pos, str2)
var_str <- insert(pos, str2)
The first variant inserts the string str2 to the string str1 at the position pos. The altered string is returned as the result; the parameter str1 itself remains unchanged. The latter variant inserts string str2 to the variable (or data item) var_str at the position pos (i.e. it changes the content of var_str). If a negative position or a position beyond the end of the string is specified, an error is returned.

Return Value

The first variant returns a string of the same type as the parameter str1.
The latter variant returns an l-value denoting var_str.
