It converts all uppercase letters to lowercase letters, except within character-string constants. There are two usual solutions to the uppercase/lowercase problem:In the C subprogram, make the name of the C function all lowercase. Compile the f77 program with the -U option, which tells f77 ...

strchrperforms case-sensitive searches, distinguishing between 's' and 'S'. The example shows different results for lowercase and uppercase searches. For case-insensitive searches, considerstrcasestr(not standard C) or convert strings to uniform case first. This behavior is important when case matters...
