Greetings,

Using ooRexx v5.0 I was reminded that in my use of rxqueue, always the text ends up UPPERCASE. Example:

CheckEXIF: procedure expose LDSLogging
THISPhotoFile = arg(1)

THISPhotoDate = ''
THISCameraBrand = ''

EXIFqueue = RXqueue('create')
OLDqueue = RXqueue('set', EXIFqueue)
'exif "'THISPhotoFile'" | /usr/local/bin/rxqueue ' EXIFqueue

do queued()
pull THISline
if THISline~left(20) = 'DATE AND TIME (ORIGI' then
do
THISPhotoDate = THISline~substr(22, 10)~changeStr(':', '')
end
if THISline~left(20) = 'MANUFACTURER' then
do
THISCameraBrand = THISline~substr(22, 1)~upper()
end
end
rc = RXqueue('delete', EXIFqueue)
trash = RXqueue('set', OLDqueue)

THISreturn = THISPhotoDate || THISCameraBrand
..output~lineout(THISreturn)
return THISreturn

I must seek for 'DATE AND TIME (ORIGI' and MANUFACTURER' instead of the exact case I see the program output. I would think passing the data through rxqueue is responsible for the UPPERCASE transformation. Or is the do queued(), pull THISline responsible and the data really is within rxqueue CasePreserved?

I am thankful,
Michael Lueck

rxqueue doesn't uppercase, but PULL does. Use PARSE PULL instead.

Excellent! Indeed using PARSE PULL preserves the caseness of the data. Thank you, Rick!
