#47 2002 STANDARD +: support for complex conditional conditions (IF directive and others)

[Simon Sobisch]

GC/OC 2.0 implements only a simple check for defines (ELIF is an extension)

::cobolfree
>> IF stuff [IS] [NOT] DEFINED
>> ELIF stuff2 [IS] [NOT] DEFINED
>> ELSE
>> END-IF

A combination via and/or (needs implementation in step 1)

::cobolfree
>> IF stuff [IS] [NOT] DEFINED AND stuff2 [IS] [NOT] DEFINED
>> ELIF stuff3 [IS] [NOT] DEFINED OR stuff4 [IS] [NOT] DEFINED
>> ELSE
>> END-IF

is missing and everything else like arithmetic expressions, too (need implementation step by step).
