 C_VINIT()

 DESCRIPTION

 The C_VINIT() function initializes the public memory variables
 created by C_VPUBLIC() to their empty values.  C_VINIT()
 initializes all data types to their correct empty values.

 NOTES

 The C_VPUBLIC() function must be called first before any other
 ClipOn database memory variable function.

 SYNTAX

 C_VINIT([prefix])

 PARAMETERS

 prefix (C) is the prefix string originally specified for C_VPUBLIC() when
 the public memory variables were created.  If prefix is not specified,
 the default of no prefix is used.

 RETURNS

 C_VINIT() returns true (.T.) if all memory variables are
 successfully initialized, or false (.F.) if an error occurs.
