Variables are flagged as errors

[LenKrause]

call "CDS069",0,0,0,0,"+As of Date+", "J", asof
if ctl=4 bye
?'cs',
json! = Payment.getOpenPayments(asof)

[StephanWald]

This is sort of expected, as your variable asof is not initialized but used without prior initialization.

Add asof=0before the CALL statement and see the error flagging gone.

To be discussed.
