USING VPLUS INTRINSICS
CALLING VPLUS INTRINSICS
The VPLUS parameters use only data types that are available in all programming
languages: character, integer, logical, and double integer. The only exceptions are the
transfer and conversion intrinsics, VPUTtype and VGETtype, which use real and long.
Each parameter is described according to its generic type (character, integer, logical, or
double integer). This table is provided for those languages that do not call their data types
by these particular names. For example, if you are coding in COBOL and a parameter is
specified as logical, you can determine from this table that it is an unsigned computational
item that uses from one to four digits.

In BASIC, a double integer can be represented by two consecutive integers:
• the first contains the high-order digits of values above 32767 or is zero,
• the second contains the low-order digits of values above 32767 or the entire value up to
32767.
