| 23 | .SH NAME | |
| 24 | fsplit \- split a multi-routine Fortran file into individual files | |
| 25 | .SH SYNOPSIS | |
| 26 | .B fsplit | |
| 27 | [ | |
| 28 | .B -e | |
| 29 | efile] ... [ file ] | |
| 30 | .SH DESCRIPTION | |
| 31 | .B Fsplit | |
| 32 | takes as input either a file or standard input containing Fortran source code. | |
| 33 | It attempts to split the input into separate routine files of the | |
| 34 | form | |
| 35 | .I name.f, | |
| 36 | where | |
| 37 | .I name | |
| 38 | is the name of the program unit (e.g. function, subroutine, block data or | |
| 39 | program). The name for unnamed block data subprograms has the form | |
| 40 | .I blkdtaNNN.f | |
| 41 | where NNN is three digits and a file of this name does not already exist. | |
| 42 | For unnamed main programs the name has the form | |
| 43 | .I mainNNN.f. | |
| 44 | If there is an error in classifying a program unit, or if | |
| 45 | .I name.f | |
| 46 | already exists, | |
| 47 | the program unit will be put in a file of the form | |
| 48 | .I zzzNNN.f | |
| 49 | where | |
| 50 | .I zzzNNN.f | |
| 51 | does not already exist. | |
| 52 | .PP | |
| 53 | Normally each subprogram unit is split into a separate file. When the | |
| 54 | .I -e | |
| 55 | option is used, only the specified subprogram units are split into separate | |
| 56 | files. E.g.: | |
| 57 | .nf | |
| 58 | fsplit -e readit -e doit prog.f | |
| 59 | .fi | |
| 60 | will split readit and doit into separate files. | |
| 61 | .SH DIAGNOSTICS | |
| 62 | If names specified via the | |
| 63 | .I -e | |
| 64 | option are not found, a diagnostic is written to | |
| 65 | .I standard | |
| 66 | .I error. | |
| 67 | .SH AUTHOR | |

| 69 | .SH BUGS | |
| 70 | .I Fsplit | |
| 71 | assumes the subprogram name is on the first noncomment line of the subprogram | |
| 72 | unit. Nonstandard source formats may confuse | |
| 73 | .I fsplit. | |
| 74 | .PP | |
| 75 | It is hard to use | |
| 76 | .I -e | |
| 77 | for unnamed main programs and block data subprograms since you must | |
| 78 | predict the created file name. |
