Statement Numbers
Transfer Statements
General
74
4. The decimal exponent following the E in a floating point constant is in-
correctly expressed in form or size.
5. The exponent following an E has been omitted.
6. Floating point number followed by an alphabetic character other than E.
STNO
1. Statement number longer than 4 digits.
2. Statement number has been previously defined.
3. Unnumbered CONTINUE statement. (Should be numbered when used as
last
statement in a DO loop.)
4. Statement immediately following a transfer statement is not numbered,
and is therefore inaccessible to the source program. (If the previous state-
ment is a transfer, the only way the program can process this statement
is by a transfer to it, and therefore it must always be numbered.)
TRANS
1. Statement numbers in a transfer statement (GO TO, computed GO TO, or
IF) are not acceptable fixed point numbers; there is no comma between
statement numbers, or there is not the required number of statement
numbers.

5.
6.
Comma missing after the right parenthesis in a computed GO TO statement.
Index
in a computed GO TO statement is not a fixed point variable, or is
missing.
Nonnumerical
character follows right parenthesis in an IF statement.
In an IF statement, a character other than a left parenthesis follows the
word IF.
No arithmetic statement within the parentheses after the IF. (However,
empty parentheses in an arithmetic statement will not be detected.)
GEN
Misspelled or unacceptable nonarithmetic statement.
Statement contains an unacceptable character.
More
than 72 characters in statement (not applicable to cards).
Symbol table full (occupies more than 2,500 digits in storage).
Statement contains decimal point that is not in a floating point constant.
Input/output statement contains no FORMAT number, or is incorrectly
stated.
7. First character in an input/ouput list is not alphabetic, or the final char-
acter is not a letter or a digit.
8. In a DIMENSION statement, a nonalphabetic character precedes the first
variable
name or a dimension, or three dimensions have been specified
( only two-dimensional arrays are
permitted).
9. A specified dimension is incorrect: a parenthesis has been omitted, a
floating
point constant or an unacceptable fixed point constant has been
used, etc.
10. Unnumbered FORMAT statement.
11. Incomplete FORMAT statement: invalid or incorrect specification, missing
parentheses,
character after right parenthesis, etc.
12. In an input/output statement, comma is missing after the FORMAT state-
ment number, or the list is missing or invalid.
13. The total record width specified in a FORMAT statement exceeds 87.
14. A variable in a DIMENSION statement has been previously defined.
15. a. The letter H orX is missingin an alphameric FORMAT statement or the
width of an alphameric FORMAT statement is greater than 49.
b. A FORMAT statement does not contain any of the specification types, I,
H, X, E, or F.
