Parameter problem calling subroutine

Parameter problem calling subroutine

Parameter problem calling subroutine

(OP)
Hi,

I am a beginner programmer in Fortran, but has to modify some code. It has to do with adding an extra parameter to a subroutine. I thought this had to be easy, but i am overlooking something and i really do not know what.
In the subroutine TNKDAT() i use the following code to call a subroutine TNKUPD():

 90   IF (IOP1.NE.16) CALL TNKUPD(VN,WN,FN,SN,LCG,TCG,VCG,FSM,IMFSM,DATE)

IMFSM is the parameter i added.

The definition of the subroutine TNKUPD is as follows:
SUBROUTINE TNKUPD(VN,WN,FN,SN,LCG,TCG,VCG,FSM,TTT,DATE)

I think it has something to do with declaring variables or the type of variables, but it is a wild guess for me...

The code will not compile and gives the following warning:
..\FORALS.NEW\O_MODB.FOR
..\FORALS.NEW\O_MODB.FOR(617) : error F2115: syntax error
..\FORALS.NEW\O_MODB.FOR(646) : warning F4999: CN : variable declared but not used
..\FORALS.NEW\O_MODB.FOR(646) : warning F4999: TRICH : variable declared but not used
..\FORALS.NEW\O_MODB.FOR(646) : error F2837: label 90 : undefined
..\FORALS.NEW\O_MODB.FOR(746) : warning F4999: CN : variable declared but not used

RE: Parameter problem calling subroutine

See misspellings (dot instead of comma etc). Where is your 617 line (-3..+3 lines too) in the snippet? Obviously, it's not an extra parameter issue...

RE: Parameter problem calling subroutine

V is next to C on the keyboard.  Have you typed CN instead of VN?

I solved the problem. It had something to do with the column the statement was in. Did not know Fortran is so sensitive....

RE: Parameter problem calling subroutine

You're probably using either Fortran IV or 77.

Fortran II, IV and 77 labels in cols 1-5, continuation in col 6, code 7 to 72

Fortran 90, 95 and 2003 are free format.
