How about this?

LongString = TEXT50;

d ExtractSpecs pi
d LongString 32000a Varying

Thanks,

Subject: Options(*Varsize) question

I've tried a couple of variations on the code snippet below, but this is the only one that compiled. In the example below, TEXT50 is a 50-char length variable. Once inside the ExtractSpecs proc, LongString shows the value of TEXT50 in the first 50 columns, but is followed by "junk".

My (apparently incorrect) understanding of Options(*Varsize) is that the ExtractSpecs proc would "see" only the value in LongString up to the length of the variable passed to it. The compile fails if Options(*Varsize) is not specified. Ditto if I used the VARYING keyword.

My kludgy, hopefully temporary, workaround is to capture the length of the first parameter and pass it as the second parameter.

Ideas / advice / specific RTFM references appreciated!

d ExtractSpecs pr
d LongString 32000a Options( *VarSize )
...
ExtractSpecs( TEXT50 ) ;
...
p ExtractSpecs b
d ExtractSpecs pi
d LongString 32000a Options( *VarSize )
