wrong offload tag code

[Alin_M_Elena]

Hi,

in the document listed here (the documentation for the latest intel fortran compiler 13.1.3)

http://software.intel.com/en-us/node/413108#30B8C09D-9EC7-401B-8CFC-E4FC3649C0AF
the code listed after (practically the last code there)
The following example demonstrates the tag argument:

contains two mistakes:
1. prevents the code to compile due to two stray #endif in the code

2. uses uninitialised values for gtag and ktag
this makes the resulting code to crash with the following message

[aelena00@node005 fortran]$ ifort -o offloadTags.MIX offloadTags.F90
[aelena00@node005 fortran]$ ./offloadTags.MIX

initialising them to some values... results in an working code

[aelena00@node005 fortran]$ ifort -o offloadTags.MIX offloadTags.F90 -DdoGLOB
[aelena00@node005 fortran]$ ./offloadTags.MIX
5.100000 5.100000 5.100000 5.100000 5.100000
5.100000 5.100000 5.100000 5.100000 5.100000
[aelena00@node005 fortran]$ ifort -o offloadTags.MIX offloadTags.F90
[aelena00@node005 fortran]$ ./offloadTags.MIX
5.100000 5.100000 5.100000 5.100000 5.100000
5.100000 5.100000 5.100000 5.100000 5.100000

I have already reported this against the documentation.

Thank you for the note Alin. The noted mistakes in this example are fixed in the documentation for the coming Composer XE 2013 SP1 release (next month).

Thank you Kevin! Great to hear that!
