What is run-time error F6501?
in [Fortran]
|
From: ian_d_chivers on 16 Jan 2007 17:25 i did a google and came up with In an application compiled with Microsoft FORTRAN, when the user responds to a keyboard READ statement with a CTRL+Z character, subsequent READ statements do not pause for input or the run-time library generates the following message: run-time error F6501: READ(CON) - end of file encountered and CAUSE When the user enters a CTRL+Z character to signify the end-of-file (EOF) condition, the run-time library sets an internal variable to indicate that the EOF has occurred. This variable remains set until the application executes a PRINT or WRITE statement. When the READ statement includes the END modifier and the internal EOF variable is set, execution branches immediately to the statement specified in the END modifier. When the READ statement does not include the END modifier and the internal EOF variable is set, the F6501 error occurs. Back to the top RESOLUTION To address this problem, use the PRINT or WRITE statement to send information to the screen and to reset the internal EOF flag prior to each READ that may receive the CTRL+Z. Using the graphics function OUTTEXT to send output to the screen does not clear the internal EOF flag. does this help? dpb wrote: > Tunjang wrote: > > i had compile and build my program and got no error...when i try to execute > > file.exe i find out that the run-time error F6501 occur...im using Window > > Xp....im using Microsoft Fortran Powerstation 4.0.. > > If you only get the error number and not the text that is associated > with it, then you either don't have the full install or are missing an > environment variable to the text of the error messages.

oohh...actually the run-time error F6501 that i got i because of my data quantity....the program is aspect to read a lots of data(about 10000 data) but i only put 365 data...after i put all my data (about 9497 data) i find out that the run-time error had gone....Tq..:) |
