read a value from a file

read a value from a file

(OP)
Hello,
I have a file that goes like this:

                                                           
  ***      MODEL RUN      ***
  *** VERSION DATED 96043 ***
.
.
.
.
STACK HT (M)           =     100.0000
STACK DIAMETER (M)     =       2.6950
STACK VELOCITY (M/S)   =      99.9020

How can I use the READ command to read the values 100.0000, 2.6950, 99.9020 and in general anything that is on the right of the = sign?

 

RE: read a value from a file

1). Read the entire line as a character string.
2). Use INDEX to find the position of = in the string
3). Do an internal free format read on the substring after the =



CHARACTER*50 STRING

READ(5,'(A)')STRING
L=LENG(STRING)
K=INDEX(STRING,'=')
READ(STRING(K+1:L),*)VALUE
 

RE: read a value from a file

Lookup namelist in your compiler documentation.  It may do something similar.
