The SADD (String ADDress) function will not accept a concatenation of
strings or a quoted literal string as a parameter. The only valid
argument for the SADD function is a single, variable-length string
variable.

This information applies to Microsoft QuickBASIC Versions 4.00, 4.00b,
and 4.50, Microsoft BASIC Compiler Versions 6.00 and 6.00b, and
Microsoft BASIC PDS Version 7.00 for MS-DOS and MS OS/2.

Under versions of QuickBASIC earlier than Version 4.00, the SADD
function accepts an argument that is a quoted literal string or a
concatenation of strings. This behavior returns the address of the
temporary storage location for the string. This is no longer allowed
in QuickBASIC Version 4.00 or later.

The following is a code example:

c$ = "This program compiles and runs"
b$ = " under Microsoft QuickBASIC 3.00"
PRINT c$ + b$
PRINT SADD(c$ + b$)
