WriteLn> and %CRLF%

[JRL]

Could there be a new WriteLn> variable that allows the text "%CRLF%" to be written without causing a line feed? Something similar to the WLN_NOCRLF variable that prevents a line feed from being added during a WriteLn>.

As an example, the following code will write a script but the resulting script will be incorrect because one line contains several instances of "%CRLF%".

Code: Select all

WriteLn>%temp_dir%temp.scp,wres,Dialog>Dialog1
WriteLn>%temp_dir%temp.scp,wres,   Caption=Write this to a file
WriteLn>%temp_dir%temp.scp,wres,   Width=204
WriteLn>%temp_dir%temp.scp,wres,   Height=236
WriteLn>%temp_dir%temp.scp,wres,   Top=0
WriteLn>%temp_dir%temp.scp,wres,   Left=0
WriteLn>%temp_dir%temp.scp,wres,   RadioGroup=msRadioGroup1,msRadioGroup1,48,32,97,105,Item1%CRLF%Item2%CRLF%Item3,-1
WriteLn>%temp_dir%temp.scp,wres,EndDialog>Dialog1

WriteLn>%temp_dir%temp.scp,wres,Show>dialog1,res1

Running the previous script will result in the following incorrect code being written to the %temp_dir%temp.scp file.

Code: Select all

Dialog>Dialog1
   Caption=Write this to a file
   Width=204
   Height=236
   Top=0
   Left=0
   RadioGroup=msRadioGroup1,msRadioGroup1,48,32,97,105,Item1
Item2
Item3,-1
EndDialog>Dialog1
Show>dialog1,res1

Thanks for listening,

Two workarounds:

1. Redefine CRLF to a plain string first:

Code: Select all

Let>CRLF={"CRLF"}
WriteLn>%temp_dir%temp.scp,wres,   RadioGroup=msRadioGroup1,msRadioGroup1,48,32,97,105,Item1%CRLF%Item2%CRLF%Item3,-1

You may still need the real CRLF later in the script so you could do:

Code: Select all

Let>realCRLF=CRLF
Let>CRLF={"CRLF"}

WriteLn>%temp_dir%temp.scp,wres,   RadioGroup=msRadioGroup1,msRadioGroup1,48,32,97,105,Item1%CRLF%Item2%CRLF%Item3,-1

//Put CRLF back
Let>CRLF=realCRLF

2. Split the string up:

Code: Select all

WriteLn>%temp_dir%temp.scp,wres,{"   RadioGroup=msRadioGroup1,msRadioGroup1,48,32,97,105,Item1%" + "CRLF" + "%Item2%" + "CRLF" + "%Item3,-1"}

1. Redefine CRLF to a plain string first:

Let>CRLF={"CRLF"}

Thanks for the ideas. I like the first one. I've been using a variation of the second one for quite a while and I've never liked it, it gets confusing. The first one is good enough that I'll rescind my request.

You may still need the real CRLF later in the script so you could do:

Let>realCRLF=CRLF
Let>CRLF={"CRLF"}

WriteLn>%temp_dir%temp.scp,wres, RadioGroup=msRadioGroup1,msRadioGroup1,48,32,97,105,Item1%CRLF%Item2%CRLF%Item3,-1

//Put CRLF back
Let>CRLF=realCRLF

Or, since CR and LF also are built in variables, there's no need to pre-save the value. You could simply do:

Code: Select all

Let>CRLF={"CRLF"}

WriteLn>%temp_dir%temp.scp,wres,   RadioGroup=msRadioGroup1,msRadioGroup1,48,32,97,105,Item1%CRLF%Item2%CRLF%Item3,-1

//Put CRLF back
Let>CRLF=%CR%%LF%
