Please find TRANSREAD.PRO on my IDL web page:
http://astrog.physics.wisc.edu/~craigm/idl/idl.html
TRANSREAD parses an ASCII table into IDL variables, one variable for
each column in the table. It can read general tabular data -- not just
numerical values -- as long as you can express it with an IDL FORMAT
expression.
Feature highlights include:
* FORMAT expression is optionally accepted.
* Comment lines can optionally be recognized and ignored.
* Standalone operation. No other IDL procedures are needed.
* Input is either a file unit or a string array.
* Start and Stop "Cue" Phrases can be used to begin and end the
parsing operation.
* Extensive documentation is included in the header of TRANSREAD.PRO
itself.
TRANSREAD behaves similarly to READF/READS in that it transfers ASCII
input data into IDL variables. The difference is that TRANSREAD reads
more than one row in one pass, and returns data by column. In a sense,
it forms the transpose of the typical output from READF or READS
(which returns data by row), hence the name TRANSREAD.
