CHOOSE returns -2 following use of INPUT THROUGH C program
PROBLEM: PROGRESS returns a -2 from a CHOOSE FIELD
PROCEDURE DESCRIPTION:
PROGRESS 4GL procedure was calling a C program that calculates
a value from parameters passed to it.
INPUT THROUGH <C program>.
{stuff}
which was later followed by CHOOSE FIELD.
By the time the CHOOSE FIELD was reached, PROGRESS is still
looking for response from the program, which of course isn't
sending anything at that point.
Add "INPUT CLOSE." to redirect input back from the _keyboard_,
or use a NAMED STREAM on the C program, e.g.,
DEFINE STREAM c-prog.
INPUT STREAM c-prog FROM library/cprocs/calculator.
SET STREAM c-prog <variable>.
