Dear all,

The problem comes from the strrs (SearchString value) when is converted to float. It could be because it is an string-ARRAY because I did not find this problem with uki1 and uki2 (using STRMATCH).
For the last example I can not understand what is happening because there is not any conversion…but the warning say: Unable to convert given STRING to Long64

If you could help me……

PROBLEM 1
*******************part of the code************************************

if country eq 'UK' then begin
uki1 = 'UKI1'
uki2 = 'UKI2'
ara90_uki1 = (float(dataclc90[WHERE(STRMATCH(dataclc90,uki1))+3]))/10000
ara90_uki2 = (float(dataclc90[WHERE(STRMATCH(dataclc90,uki2))+3]))/10000
pc90_uki1 = (float(dataclc90[WHERE(STRMATCH(dataclc90,uki1))+4]))/10000
pc90_uki2 = (float(dataclc90[WHERE(STRMATCH(dataclc90,uki2))+4]))/10000
past90_uki1 = (float(dataclc90[WHERE(STRMATCH(dataclc90,uki1))+5]))/10000
past90_uki2 = (float(dataclc90[WHERE(STRMATCH(dataclc90,uki2))+5]) )/10000
endif

ara= float(dataclc90[WHERE(STRMATCH(dataclc90,strrs))+3])
araclc90=float(ara)/10000
pc= float(dataclc90[WHERE(STRMATCH(dataclc90,strrs))+4])
pcclc90=float(pc)/10000
past= float(dataclc90[WHERE(STRMATCH(dataclc90,strrs))+5])
pastclc90=float(past)/10000


****************************console************************* ************
IDL> help, uki1
UKI1 STRING = 'UKI1'
IDL> help, strrs
STRRS STRING = Array[1]



PROBLEM2
******************part of the code************************************

% Type conversion error: Unable to convert given STRING to Long64.

printf,1,uki2
for y=0L, nyears+4 do begin
printf, 1, ['dummies','noData',$ //This is the line 965
'noData','noData','noData', $
'noData','noData','noData'],$

Thank you very much for your time.

These are *strings* you are trying to print (e.g., "dummies", "noData",
etc.), not integers as your FORMAT statement would indicate. IDL is
complaining because you are sending it mixed messages. :-)

Cheers,

David

Thank you very much for answering.
The code is not mine, and I do not know how to fix this problem.

Well, you need to match the type of data you are printing with the
proper format code. The format code for strings is "A" not "I", which is
the format code for integers. Try looking up "format codes" in the IDL
on-line help.

Cheers,

David

Thank you very much David.
I will check in the IDL on-line help.
