No, it is easy. It is enough to locate the variable (using SymFind
for example), and to display its content using BitmapPut (its
contents are just as expected by BitmapPut function). To be
more concrete, look at the following function:
short show_picvar (SYM_STR SymName, short x, short y, short Attr)
{
SYM_ENTRY *sym_entry = SymFindPtr (SymName, 0);
if (!sym_entry) return FALSE;
if (peek (HToESI (sym_entry->handle)) != PIC_TAG) return FALSE;
BitmapPut (x, y, HeapDeref (sym_entry->handle) + 2, ScrRect, Attr);
return TRUE;
}
The usage of this function is straightforward, for example:
show_picvar (SYMSTR ("testpic"), 30, 30, A_NORMAL);
assuming that "testpic" is the name of the wanted PIC variable. This function returns
TRUE if the operation was successful, else returns
FALSE (i.e. the picvar does not exist, or it is not
a PIC variable).
