Status: Verified
FACT(s) (Environment):
Webspeed
SYMPTOM(s):
WebSpeed error from messenger process (6019)
WebSpeed Agent Error: Agent did not return an HTML page (6383)
Trying to run 4GL Code
FIX:
Those wishing to web-enable existing 4GL applications should keep in mind the subset of Progress Keywords which are invalid when used in WebSpeed SpeedScript. Errors or unpredictable results can result when these keywords are used in SpeedScript.
The Progress Version 9.x Language Reference Manual provides a chart with each statement, function, or phrase indicating whether it can be used in SpeedScript. The table below summarizes those entries which are disallowed for Speedscript.
In some cases, existing 4GL syntax that contains these keywords may be made conditional by including the preprocessor &IF to check for "Webspeed" in the return value of PROVERSION.
