|
|
* =============
|
|
*>
|
|
*> \verbatim
|
|
*>
|
|
*> This subroutine translates from a character string specifying a
|
|
*> transposition operation to the relevant BLAST-specified integer
|
|
*> constant.
|
|
*>
|
|
*> ILATRANS returns an INTEGER. If ILATRANS < 0, then the input is not
|
|
*> a character indicating a transposition operator. Otherwise ILATRANS
|
|
*> returns the constant value corresponding to TRANS.
