SYMPTOMS
An attempt to compile a program that contains nested $IF compiler conditions with $ELSE clauses may fail to produce the expected result. The compiler may generate the error:

error F2830: END missing



CAUSE
When there is a $ELSE following a $ENDIF and the outer $IF condition is met making the condition false, the compiler fails to parse for any metacommands following the $ELSE including the $ENDIF that terminates the outer $IF block.



STATUS
Microsoft has confirmed this to be a problem in Microsoft FORTRAN PowerStation 32 for Windows NT, version 1.0 and MS-DOS versions 1.0 and 1.0a. This problem was fixed in FORTRAN PowerStation, version 4.0.



MORE INFORMATION
The sample code below illustrates the problem:

Sample Code
C Compile options needed: none $define first subroutine test $if defined (first) $if defined (second) $endif $else $endif return end
