Abstract: WDATA is a subroutine for writing absolute binary data on

the OS/8 SYS-device.

Format: Sequential blocks of 400g data words per block.

By means of 'USR' the user opens his data-file and then WDATA

writes the buffer contents to the sys-device (start address, field, and length

of buffer programmable). For subsequent calls to WDATA no new data-

filename is necessary; WDATA keeps track of the block-numbers.

Furthermore, it examines if the buffer length corresponds to an even

number of pages, if the sys-space available is sufficient for the next buffer

output (if not, a correction will be done of the amount of output together

with a correction message), and it asks after a successful buffer-output if

you want to transfer any more data. If your output has been ended it will

print out the complete filename (with the extension ".EX") and its total

block length.

Evaluations of these data having been stored on sys by WDATA can

be made in FORTRAN II by means of the program USLIBA (DECUS

8-759).
