FACT(s) (Environment):
Windows
SYMPTOM(s):
OS-GETENV does not return values including some characters on Appserver
OS-GETENV returns null value when retrieving an environment variable defined on the Appserver, that has an '@' or '$' symbol in its value.
Environment variables defined like:
ReplyTo = bla@progress.com
fail to return a value with OS-GETENV.
CAUSE:
This is expected bahaviour.
The ubroker.properties file uses $ and @ to represent substitutions for environment variables and registry settings. The comments in the ubroker.properties file explain this:
# Comments indicate which properties you cannot modify. Many properties have
# pre-defined defaults. Environment variables are valid for all properties
# (both numeric and character) using the standard conventions - $ENVVAR or
# ${ENVVAR}. Also, the escape character is supported (e.g \$) so that
# you can include a '$' as a keyword value.
# In addition to environment variables, Registry values are also supported.
# The syntax for specifying a value from the registry is @{Key\Value}.
# Where 'Key' is a registry key off the PROGRESS base key:
FIX:
To resolve this problem precede the character causing the problem with the escape tilde character to force Progress to interpret is as a character literal. For example with an environment variable defined as:
ReplyTo=bla~@progress.com
OS-GETENV('ReplyTo') returns 'bla@progress.com'.
