1. What the heck does this mean?
Okay, I'm stumped. I've got the following routine:
global function ecarc_rtvDataArea(sequence system_name, sequence
data_area_lib,
sequence data_area, atom starting_pos,
atom length, sequence dtaara_def)
sequence parm_str
atom parm_length
parm_length = length(dtaara_def)
-- We'll need to form the BEGSTR sequence using the parameter structure
-- supplied to this routine
parm_str = ecarc_makeStructure(QWCRDTAA_RtnVar & dtaara_def,
"DTAARA_RcvVar")
parm_str &= QWCRDTAA
-- Call the retrieve data area API
parm_str = ecarc_call(system_name, "*LIBL", "QWCRDTAA", parm_str)
-- If the parms returned is a sequence, return the 8th parm for the
length
-- of the passed parm structure
if sequence(parm_str) then
return parm_str[8..(8 + parm_length - 1)]
else
return ""
end if
end function
That when included in a program (a rather large proram), generates the
following error:
C:\Program Files\F.R.O.G. for IBM iSeries DB2\eucarc.ew:1025
Syntax error - expected to see possibly 'end', not '('
parm_length = length(dtaara_def)
^
If I comment the line out it runs fine.
HELP!!!!!!!!!!!!!!!1

You can't have an "atom" named "length," right?

^^^^^^
You've overridden the builtin length() function. I assume you are
running "without warning" otherwise Euphoria would give you a warning
about this when the program ends.

I think the list is technically complete. Somewhere in the docs Rob
explains a technique for overwriting a builtin function and calling
the original, I believe something like this:
function original_length_function(sequence x)
return length(x)
end function
function length(object x)
if not sequence(x) then return 0 end if
return original_length_function(x)
end function
