Simple Variables
The following syntax refers to a simple scalar-valued variable (integer, floating-point, or character string):
simplename
Syntax Notes:
• If you use the variable to send values to Ingres, it can be any scalar-valued variable or ##define constant, enumerated variable, or enumerated literal.
• If you use the variable to receive values from Ingres, it can only be a scalar-valued variable or enumerated variable.
• Character strings that are declared as:
char *character_string_pointer;
or:
char character_string_buffer[];
are considered scalar-valued variables and should not include any indirection when referenced.
• External compiled forms that are declared as:
UNIX:
extern int
*compiled_formname; 
VMS:
globalref int *
compiled_formname; 
should not include any indirection when referenced in the addform statement:
## addform compiled_formname;
The following example shows a message handling routine. It passes two scalar-valued variables as parameters: "buffer," a character string, and "seconds," an integer variable.
## Print_Message(buffer, seconds)
## char *buffer
## short seconds
## {
## message buffer
## sleep seconds
## }
