cfbioserrsis an integer expression specifying the number of bytes involved intranslation.is the format-specifier.is a scalar or array reference for the buffer area receiving formatted data(characters).is an integer scalar memory reference which is the input/output statusspecifier: if this is included, ios becomes defined with zero if no errorcondition exists or a positive integer when there is an error condition.an error specifier which takes the form of a statement label of anexecutable statement in the same program. If an error condition occursexecution continues with the statement specified by errs.lista list of output items.Non-character Format-specifier §If a format-specifier is a variable which is neither CHARACTER nor a simple INTEGER variable,the compiler accepts it and treats it as if the contents were character. For example, below sum istreated as a format descriptor:real sumsum = 4h()accept sumand is roughly equivalent tocharacter*4 chch = '()'accept chSee AlsoREAD, PRINTEND 77The END statement terminates a segment of a Fortran program. There are several varieties of theEND statement. Each is described below.END SyntaxEND82 Chapter 3
DescriptionThe END statement terminates a module. The END statement has the same effect as a RETURNstatement in a SUBROUTINE or FUNCTION, or the effect of a STOP statement in a PROGRAMprogram unit. END may be the last statement in a compilation or it may be followed by a newprogram unit or module.END DO SyntaxThe END DO statement terminates a DO or DO WHILE loop.END DODescriptionThe END DO statement terminates an indexed DO or DO WHILE statement which does notcontain a terminal-statement label.The END DO statement may also be used as a labeled terminal statement if the DO or DO WHILEstatement contains a terminal-statement label.END FILE SyntaxEND FILE uEND FILE ([UNIT=]u, [,IOSTAT =ios] [,ERR=errs] )uIOSTAT=iosERR=errsis the external unit specifier where u is an integer.an integer scalar memory reference which is the input/output specifier:if this is included in list, ios becomes defined with zero if no errorcondition exists or a positive integer when there is an error condition.an error specifier which takes the form of a statement label of anexecutable statement in the same program. If an error condition occursexecution continues with the statement specified by errs.DescriptionWhen an END FILE statement is executed an endfile record is written to the file as the nextrecord. The file is then positioned after the endfile record. Note that only records written prior tothe endfile record can be read later.A BACKSPACE or REWIND statement must be used to reposition the file after an END FILEstatement prior to the execution of any data transfer statement. A file is created if there is an ENDFILE statement for a file connected but not in existence.Fortran Statements 83
