Subject:      Can SYSGET result be quoted?

Hi:

Consider the situation when a system environment variable has a value that
contains an ampersand:
  SET EXTERNAL_PARAMETER="THIS&THAT"
or the system properties dialog is used to assign
  name: EXTERNAL_PARAMETER
  value: THIS&THAT

The following code will log
  WARNING: Apparent symbolic reference THAT not resolved.

%let value = %sysget(EXTERNAL_PARAMETER);

Is there a way to quote or prevent macro resolution of sysgetted values ?

A similar warning appears when using SYSGET in DATA Step:
  call symput ('value', system('EXTERNAL_PARAMETER'));

Thanks,
Richard
