pointer function lsjoin (ptr1, ptr2)
pointer ptr1, ptr2

Library:  vlslb

The string specified by 'ptr2' is concatenated to the end of the
string specified by 'ptr1'. A pointer to the resulting string is
returned in 'ptr1' and as the function value. 'Ptr2' ceases to be
a valid pointer.
.im
The string specified by 'ptr1' is positioned to its end.  Then the
EOS character in the first string is replaced by 'ptr2' + 300, thus
linking the second string to the first.
