The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

Given the following block of code:
C CLEAR LFPOS 5 0
C EVAL LFPOS = %SCAN(X'0A':EVENTDTLX)
C DOW LFPOS > 0
C EVAL EVENTDTL = %REPLACE('\n':EVENTDTLX:LFPOS:1)
C EVAL LFPOS = %SCAN(X'0A':EVENTDTLX)
C ENDDO
and the following data in EVENTDTLX:
00000 C9409389 928540A2 9781944B 0A0AC940 - I like spam...I
00010 93899285 40A29781 944B0A0A C9409389 - like spam...I li
00020 928540A2 9781944B 40404040 40404040 - ke spam.
I get completely different behavior, depending on whether it executes in
an interactive job or in a server job:
In an interactive job, it behaves correctly, replacing each hex '04'
byte (an ASCII linefeed; not quite sure what it is in EBCDIC) with a
backslash and a lowercase 'n', producing a final value for EVENTDTL of
"I like spam.\n\nI like spam.\n\nI like spam."
But in a server job, the %REPLACE is evidently doing absolutely nothing,
as if it's somehow treating the '\n' the way C would treat it (an escape
sequence representing a linefeed), with the result that this thing
tightloops.
Has anybody ever heard of such a thing happening?
The server program uses HTTPAPI to call the Google Calendar web
services, while the test program I executed on a terminal makes no
explicit external calls whatsoever.
