Seems to work with VAC3, fails with VAC4. Why?
Probably a basic error, an outdated copied coding style and/or a VAC4
error. No fixpaks installed, I just gave it a try.
#define MAXDAYS 264
typedef struct _TRADE1 {ULONG date;} TRADE1;
TRADE1 *trade1;
if (NULL==(trade1=malloc(MAXDAYS*sizeof(TRADE1))))
[Msg] CPP0216E: An expression of type "void*" cannot be converted to
"_HAND1 *".

To be safe write if (NULL==(trade1=(TRADE1*)malloc(MAXDAYS*sizeof(TRADE1)))) Marcel

I'll try to verify that later, I restored the system after having seen
v4 for OS/2 for the first time (not enough disk space on all systems
to allow for several installed compilers anyway). I did use the IDE,
so it could be some default setting indeed.

Translation error ("_TRADE1 *") by me in the error description, but it
didn't matter.

knowledge++; thanks!
