See also Soflow (disambiguation).
The SOFLOW error condition can be specified at the end of a program statement, in an Exit statement, and in the ON error statement.
SOFLOW traps the following three errors:
- 1.) The number of input data characters is greater than the defined length of the string variable used for assignment in READ, REREAD, INPUT, or LINPUT statements.
- 2.) The length of the string expression in the I/O list is greater than the field width defined in the FORM statement's format specification.
- 3.) The length of an assigned-from string (B$ in A$=B$) is greater than the dimensioned length of the assigned-to string (A$).
