* programmer - steve hankin
* NOAA/PMEL, Seattle, WA - Tropical Modeling and Analysis Program
* V230: 3/3/92
* V300: bug fix: check if expanded length is within allowable limits
* V314: 8/22/94 *kob* IBM port - needed to add ifdef MANDATORY_FORMAT_WIDTH for
* I format descriptor
* V420: 10/5/95 - bug detected in syntax var2[d=1]- VAR1[d=2,G=[VAR2[D=1]]
* - actual bug was that i1 is improperly set in branches to 10
* 2/03 *kob* - g77 port - g77 won't allow intrinsic functions in PARAMETER
* statements. use an octal constant instead
* *acm* 3/12 6D Ferret (common uses nferdims in tmap_dims.parm)
