- Added SPtrimString function to remove leading and trailing whitespace.
Used this in checkCompatibility method for arf, pha, and rmf to avoid incorrect
failure flagging due to leading or trailing blank spaces. (bug 2.2c)
- Added version of SPwriteKey to write to the primary header
and modified SPwriteKey for string values so it automatically uses the
CONTINUE convention if the string is more than 68 characters.
