Assume the following string variables exist and are defined as indicated:VariableDefinitionHostnameBLUESKYASample stringDay 28String substitution involves the replacement of a string variable by its currently assigned value. Therefore,performing string substitution on these variables within the TEXT command, produces the following results:eFT> text {hostname}.eFT: BLUESKY.eFT> text {a}.eFT: Sample string.eFT> text {day}.eFT> 28.A string function refers to one of the NetEx/eFT defined functions that may accept strings as parameters andreturn a string as a result. A few simple string functions with sample arguments appear below:date()upper("this is a test")cmp("good", "bad", "Compared", "Didn't compare")Performing string substitution on these example string functions result in the following:eFT> text {date()}.eFT: Sun Apr 2, 2011.eFT> text {upper("this is a test")}.eFT: THIS IS A TEST.eFT> text {cmp("good", "bad", "Compared", "Didn't compare")}.eFT: Didn't compare.Although the TEXT command was used in all of the examples above, string substitution can be performedanywhere within a NetEx/eFT command line, whether it is part of another NetEx/eFT command, or on a lineby itself. It’s important to remember that the result of any string substitution is simply another string. Therefore,the resulting string could even be a NetEx/eFT command.String VariablesNetEx/eFT variable names can be from one to twenty alphanumeric characters long, including underscoresand similar special characters. There are two types of variables, local and global. A local variable exists onlyREF-eFT213-R5.4-08 Advanced Local User’s Guide Page 63
