问题
I have a block of code that I want to #include in my z/OS Metal C program, it works fine when it's just part of the program, but when I put it into a .h file and #include it, the code won't compile.
I have successfully gotten this code to work without #include. I'm sure I'm overlooking something having to do with #include...
This code works:
#pragma margins(2,72)
*#if 0!=0
Test DSECT
Test@ DS A
TestINT DS F
TestChar DS C
.ago end
*#endif
*struct Test {
* void *Test1;
* int TestInt;
* char TestChar;
*};
*#if 0!=0
.end
MEND
*#endif
#pragma nomargins
Giving compiler output that looks like this:
207 |#pragma margins(2,72)
207 +
208 |#if 0!=0
214 |#endif
215 |struct Test {
216 | void *Test1;
5650ZOS V2.1.1 z/OS XL C 'SSAF.METALC.C(CKKTHING)'
* * * * * S O U R C E * * * * *
LINE STMT
*...+....1....+....2....+....3....+....4....+....5....+....6....+
217 | int TestInt;
218 | char TestChar;
219 |};
220 |#if 0!=0
223 |#endif
224 |#pragma nomargins
But, when I put the code into an #include file like this:
EDIT SSAF.METALC.H(CKKTEST)
Command ===>
****** **************************
000001 *#if 0!=0
000002 Test DSECT
000003 Test@ DS A
000004 TestINT DS F
000005 TestChar DS C
000006 .ago end
000007 *#endif
000008 *struct Test {
000009 * void *Test1;
000010 * int TestInt;
000011 * char TestChar;
000012 *};
000013 *#if 0!=0
000014 .end
000015 MEND
000016 *#endif
****** **************************
and include it in my Metal C program:
EDIT SSAF.METALC.C(CKLTHING) - 01.00
Command ===>
000205 #include"ckkprolg.h"
000206
000207 #pragma margins(2,72)
000208 #include"ckktest.h"
000209 #pragma nomargins
I get a bunch of error messages:
205 |#include"ckkprolg.h" /* Include assembler macros needed
206 | for Metal C prolog and epilog */
207 |#pragma margins(2,72)
207 +
208 |#include"ckktest.h"

The include file is missing #pragma margins. Since it is a file level directive, it needs to be present in each source file. Please see IBM Knowledge Center, which says, "The setting specified by the #pragma margins directive applies only to the source file or include file in which it is found. It has no effect on other include files."
