WebRECL=rcl rcl is an integer variable that is assigned the record length of the records in the file if the file is connected for direct access.f77 does not adjust the rcl returned by INQUIRE.The OPEN statement does such an adjustment if the -xl[d] option is set. See "Details of Features That Require -xl[d]" for an explanation of -xl[d].If no file is connected, rcl is set to -1. WebApr 30, 2024 · The RECL argument in the OPEN statement expects different values for reading and writing. In order to write a file, the whole data size must be given (in this case, 1024 bytes), while to read, the size of a single record (1 byte) has to be set. So, as you point above, use RECL=1 for reading. BTW, the ACTION='READ' spec is also non-F77, AFAIR. btc inflow data
