+        subroutine fttrec(string,status)
+
+C       test the remaining characters in a header record to insure that
+C       it contains only pri-ntable ASCII characters,
+C       i.e., with ASCII codes greater than or equal to 32 (a blank)
+C       Note: this will not detect the delete character (ASCII 127)
+C       because of the difficulties in also supporting this check
+C       on IBM mainframes, where the collating sequence is entirely
+C       different.
+
+C       string  c*72 keyword name
+C       OUTPUT PARAMETERS:
+C       status  i  output error status (0 = ok)
+
+C       optimized in 7/93 to compare "ichar(string(i:i)) .lt. space"
+C       rather than                       "(string(i:i)) .lt. ' ' "
+C       This is much faster on SUNs and DECstations,
+C       and decreases the time needed to write a keywor (ftprec) by 10%.
+C       This change made no difference on a VAX

+        integer space
+C       The following line won't compile with the Lahey compiler on a PC

+C                 illegal character found
