Just looking at the code, the procedure is getting the data passed into the variable pText, while the function is writing wkText and the incoming data is not being set into wkText.

Subject: fputs() in RPGLE

I am having a brain freeze on using fputs() in an RPGLE program. It needs to be in old-style /free format for another user.

I have this and it is showing 18 bytes written (retBytes) but the IFS file (in /tmp) is zero bytes - checked with Windows Explorer and wrklnk.

I must be missing something very obvious. Thanks.

// call proc to call _C_IFS_fopen mode 'w'

TextData = 'One Line Of Data' ;
TextBytes = IFS_Write(TextData : TextFileHandle);

// invoke proc to call _C_IFS_fclose

d pHandle * value

d retBytes s 10i 0 inz
d wkText s 32767a inz
d CRLF s 2a inz(x'0D25')

wkText = %trim(pText) + CRLF + x'00';
retBytes = Sys_IFS_Write(%addr(wkText) : pFileHandle);
if retBytes = 0;
dsply ('fputs error - Errno = CPE' + %editc(getErrno() : 'Z'));
endif;

return retBytes;

p IFS_Write e
