In the vbib-32.bas module that is included in your GPIB project, integer I/O calls (ibrdi, ilrdi, ibwrti, and ilwrti) are provided for users who need to perform arithmetic operations on the data and want to avoid the overhead of converting to the character strings required by ibrd and ibwrt and back into the integer format for the arithmetic operations.
ibrdi and ibwrti are passed data in the form of an integer array, instead of a character string. Using these functions, you can access the data directly as integers instead of defining them as characters and then converting each pair of characters to an integer. Internally, the ibwrti function sends each integer to the GPIB in low-byte, high-byte order. The ibrdi function reads a series of data bytes from the GPIB and stores them into the integer array in low-byte, high-byte order.
Hope this information is helpful.
