-b Ignore leading blanks.
-c Use card image mode.
-tx Use x as the field delimiter (default is white space).
-Pxxxx Pass any lines that begin with xxxx through unchanged. This can be used as a handy way to preserve headings.
-d Set debugging messages.
Cnn move to output column n.
S[n] insert n Spaces at current position (default 1).
T[n] insert n Tabs.
B[n] insert n vertical Bars (|).
Pxxx Print xxx.
m.n:j[(function)] NormalMode: pick up logical column m, offset n, for length j and insert into output. Cardmode: pick up physical column m for length j (n is ignored). An optional function may be applied to the selected input data. The functions are.
toupper Convert the value to upper case.
tolower Convert the value to lower case.
~ Transpose the case of the value.
base(n) Convert the (integer) value of the field to base n (n <= 82);
len Emit the length of the value.
m+[(function)] as above, but pick up data from the designated column through the end of the input line. recol is a filter that reformats an input stream as specified by a script on the command line. It is meant as an easier to use alternative to awk and perl for many common reformatting jobs. (Actually, I originally wrote it for MS-DOS in 1982 because awk and sed were not available on that platform.) It can treat input as card images or separator delimited fields. The overall process is to read a line into a work buffer, apply the operations specified on the command line to build a new line image, then print the new image.

BUGS Column numbering starts with 0 rather than 1, but that's only a bug if you aren't a (real) programmer.
