WRITE (expr{,...,expr});           Output ASCII processed data file

The WRITE procedure outputs a time tag and successive values calculated
for each 'expr' in WRITE's calling parameters to whatever system file
has been specified by the last FILE control statement.  If an X axis
file has been specified then the "time tag" for each associated value
is the corresponding X axis file value.  One time tag value is output
at the start of each line followed by values for each 'expr'.  The
line is then terminated with carriage return and line feed ASCII codes.

One header record is output followed by however many data records it
takes to hold all the data values and associated time tags.  Output
records contain ASCII values so the files can be transferred to systems
that do not use compatible floating point numbers.  The Output File
Record Structures section in your manual gives the format for each of
these record types.

The READ function is capable of processing a file created by the WRITE
procedure.

The XFORMAT and YFORMAT controls affect the format of the time tag and
data value fields, respectively.
